Once upon a time, there was a town in Mexico called El Paso. But at the end of the Mexican-American War in 1848, it was divided in two. The northern side became part of the US, and the southern side became Juarez. Spider Man has many superpowers. I really hope he's developed the ability to regulate body temperature in an all-in-one nylon suit in 90 degree heat. Since 2008, the city has been divided by a 57-mile section of border wall. Even so, thousands of people come and go across this border every day, inhabiting both worlds. On the Mexican side today, in the northern outskirts of Juarez, is a training session for a spectacle that strikes fear into my bones. This is escaramuza, a kind of souped-up Mexican dressage practised by women. Horses. Weird, skittish things. Rolling eyes. Massive moustaches. Measured in hands, don't approach them from the front, don't approach them from the rear. I'm really frightened of horses. And we're going to see some horses. I've come to meet a group of riders whose lives straddle the border. Hi, how you doing? Good. I'm Sue. Nice to see you. They live on the American side, but cross into Mexico several times a week to train with their horses. ALL: Hi! Oh! SUE GIGGLES NERVOUSLY Nice to see you. Yeah, don't stand there! Do you want a hand? Do you need any help? Yes. I can brush. I'm good at manual labour. You can start with that one. Oh, what's this one called? It's My Queen. My Queen? Oh, OK. Oh... I'm really scared of you, but it's OK. THE OTHERS LAUGH Do they like being... Ooh! I was too close to the special area there, I think. I think we can leave... I don't think that needed a brush. I don't know why I went there. I don't know why I did that. If there's one thing that scares me more than horses, it's a floral dress. OK, so this is your dress. Are you going to wear it? Well, I wasn't expecting that, but, er, yes, absolutely, I'm going to wear that. Absolutely. Yup. Really got stymied there, won't lie, won't lie, really got lured in. I mean, I was born for this. Escaramuza celebrates the female soldiers, known as adelitas, who went in to battle in the American Revolution in the early 1900s and were key in overthrowing the dictatorship government. Fearsome and uncompromising. Yep, that's me all over. I look like I should be sitting atop an enormous loo roll. I've achieved peak doily. All dressed up and somewhere to go, we head to the stadium. This is the closest I've ever got to a feeling of nobility. I'm a long way from Croydon right now. Oh, my word. This is extraordinary. It's like synchronised horsey-ing. Escaramuza translates as "skirmish", and I can see why. Demonstrations involve eight female riders carrying out tightly choreographed moves with little room for error. Riding side-saddle, it's part sporting event, part living history, with national championships taking part across Mexico each and every year. That was absolutely incredible. Oh, thank you. Thank you! You can see the horses sweating but you guys looked perfect. You look like supermodels. It's unbelievable. I want to ask about what you do outside of the arena. So what's life like off a horse? I live in El Paso, Texas, but I come across every day to practise, and then I have my dad lives here still, and my friends are here, so for us, it's pretty common to back and forth between Mexico and the US, cos it's close together, I mean, it's just the border. And do you have dual citizenship? I do, I am a dual citizen. I'm Mexican and US citizen, both of them. So America is for work and Mexico is for passion? Exactly. I am from Mexico, I'm, exactly, Mexican, 100%. Like, our hearts belong to Mexico. It's interesting, cos you see these places are so distinct, you know, so the United States and Mexico and then the wall and... But you guys, you just, your life is completely between the two? Exactly. It is. I mean, it wouldn't be complete if we were not, like, on both sides. And for us, it's just, like, natural. I love both countries. I mean, they're so different, and I've lived here all my life but I also studied over there, like, all of my life, so it's, like, I can't choose. It's, like, I'm both. I'm literally both of the countries, both of the culture and everything. Well, bearing in mind you said that you think people are better for being on horses, do you want to help me? If I put a helmet on, would you help me get on a horse? Of course. Yes. Let's do it. Let's do it. Time to confront my fears on a horse that's, rather surprisingly, called Kevin. Opa! Hola, Kevin. And then you put this leg here. This leg here? Yes. Yes, you can do it. Like that. Like that? Yes. Kevin's on the move. Kevin, don't go into a routine, Kevin, don't go into a routine. Kevin? Kevin, don't go into a routine. Ah, Kevin. Kevin, Kevin. Kevin. Kevin! Kevin, where are we... I just... I just did a little 360 on Kev. You're going about. Whoa! SUE GIGGLES Unbelievable! I'm not frightened of horses any more. There you go. It's perfect. He's beautiful and gentle. These women are living proof that people can take pride in two identities, in what both sides of the border have to offer. As professional women of means with dual citizenship, they get to enjoy the best of two very different worlds. But not everyone has the freedom they have to come and go. On the American side of the border, I'm meeting a family going to extraordinary lengths to give their children that simple right of free movement. It's hard to imagine we're actually in Texas. It feels so Mexican, this place. Hola. Hola! This is Gabriela, who's been bringing up her kids alone here in El Paso because her husband cannot legally reside in the States and is stuck on the Mexican side. Do you think he'll ever be able to get settled status in the US or do you think...? He will never have the chance to become a US citizen. It doesn't matter that we have three US citizen children. It doesn't matter that my middle one was born with a congenital heart disease, it doesn't matter. What does that mean for your relationship, for your marriage, for your love? What does it do to that? It's hard. Can I ask... I don't want to upset you at all. No, it's OK, it's OK. But I just... I suppose the question that stupid people like me would ask, would be, why don't you then all go and live together in Mexico? Because my children are US citizens. Abraham was born with this disease. He is going to have heart surgeries for life, so now I am putting my own interests to the side. If it was only for me, I would have been in Juarez long time ago. It's not only about me. I'm working hard to put food on the table and these children could be the next doctor, the next president, the next engineer... Why not? ..that this country needs. Do you want to be president? Yes. I'm going be president when I grow up. If I was a citizen, I'd vote for you. Thank you. And what would be the first thing that you would do if you were president? I would take down the wall. I know it's... I know it can be something really hard to do. It's just something... I mean, I'm still a teenager and that's how I think. I don't want that wall. Despite being physically separated, Gabriela and her husband Adrian are doing all they can to keep their family together. Every weekend, she takes the children to the border, so they can cross into Mexico and be with their dad. You're afraid? I'm afraid of any officers telling me that I can't go that far. But it's terrible that you should feel anxiety, just walking along an American sidewalk. Yes. It's horrible. They make you feel like you're a criminal, like you did something so bad that you deserve to be punished. Adrian is waiting just 300 metres away, but Gabriela is not allowed to cross the border until her own immigration papers are finalised. See, I'm doing proper... ..shielding. I got you. I got you. They're not going to come for you. In the last six years, she's spent just 15 minutes with her husband. Have a really good trip. Enjoy your weekend. Thanks. Enjoy your weekend. Thank you. Come on, I'm coming in. Have a fun time. You too. And so he'll be waiting the other side? Yes. It feels weird being so close to where my husband is and not being able to just cross that. I hope you have a happy outcome, that's all I want for your love story. Doesn't everybody? Yes, of course... SIRI SPEAKS ON GABRIELA'S PHONE I'm not talking to you, Siri! THEY LAUGH Siri, gives this beautiful Mexican woman a Hollywood, sort of, love story ending. Thank you. Siri's had a meltdown. Yes! Thank you. Thank you. Thank you so much. This narrative is familiar to anyone who's separated from their partner. But you add this, this hostile state apparatus, you add armed border patrols, you add invasive questioning, you add the idea of being criminalised for simply wanting to go and see a parent. I don't know how she does it. I do not know how Gabriela does that, because just being in this proximity I'm going to bawl my eyes out, and it's not my reality. I catch up with the kids on the Mexican side, once they've meet up with their dad. So this place feels very, very different to El Paso. Yeah. I really like the culture. I feel like I'm more Mexican than American. I can see why you love it. Yeah! It's nice. Adrian was deported from America after time in jail for immigration offences. If he tries to go back, he'll most likely end up in prison again. So, Adrian, how was your weekend? And how do you feel, when it gets time to go back across and... I hate it, really. Not being able to go back with my dad, together. Now we're all going to go, so... DAUGHTER LAUGHS I don't really talk about it, so it's hard. But that's again awful, because there is no... There's no place for you to talk about it, and people so want to just think there's the States and there's Mexico, they don't think about the people who fall between, who are on the borders, or who have family on both sides and who are permanently being torn. And I'm really sorry that's you, and I really hope it changes. Mm-hm. I hope so, too. Adrian and Gabriela think it could be four years before her status allows them to see each other again. However, their kids will continue to come and go as citizens of a single Tex-Mex super city that straddles the wall. * This is lucha libre, freestyle wrestling. Next to football, it's the biggest sport in Mexico... Mexico! ..and before I carry on my journey eastward, I've got to check it out. Oh, come on. Come on. This is the sort of thing the Pope wears when he gets down and dirty. Fight me. This one's great because it's really drawing up the double chin, so what it's done is actually given me a jawline for the first time in a decade, so I'm happy, I'm happy with this. Lucha libre became popular on TV in the 1950s. Oh, this is great. Doctor Wagner. At the beginning, it was dominated by men, but it wasn't long before women got in on the action. Hola! Nice to see you. I'm Sue. Lady Diamond. Lady Diamond, it's nice to see you. Yes. I have found my look. Nice! What do you think? Is it scary? Yes! For all the wrong reasons, right? THEY LAUGH Tell me about Lady Diamond. Is Lady Diamond a good-- is she a good human being? I'm a baby face. So what is baby face? That I'm the good guy. OK. So what is your big ambition? What do you want to do in wrestling? To be a legend, erm... SUE LAUGHS That is brilliant! I want to be recognised with, erm, the whole world, like, everywhere. Lady Diamond is yet to hit the big time in wrestling, and still performs in small, local venues, But tonight, there's a new wrestler in town... ..The Perkinator. Sue likes crisps, and she knows a bit about Jacobean tragedy and Renaissance literature. But The Perkinator, that's different. Now the mask is on, I'm a stone-cold killer, baby. Ow! Ow. Lady Diamond has agreed to show me the ropes. Please get me out of here, I'm terrified of her. Right! Yeah, I don't need that anyway, because that's getting in the way. Ow! Ooh, yep. OK. So you break the arm and then I get up? Good. Both ways, it snaps. Ooh! Si. Ooh! You're going to go down. Ow! Blargh! OK? Ooh! MUFFLED: I think she's got me cos I wasn't expecting that. ANNOUNCER: Lady Diamond! It's time for the main event. CHEERING Lady Diamond is the star attraction. SUE: Woo! Yay! Come on! Lady Diamond's mum, Mrs Diamond. Yay! I'm Lady Diamond! What she said! SHOUTING AND CHANTING I love that this feels like a homespun, school hall version of what you'd get in the big stadiums, and it's completely bonkers. SUE LAUGHS HYSTERICALLY This is the most random thing I've ever attended. Yay! Just when I thought the fight was finished, it turns out it's only just beginning. Whoa! No, not the chair! No! Right, this is now developing into a brawl. I don't know where entertainment ends and just pure, unabated, intergenerational violence begins, but we're at that sweet spot. Right. I'm going to go before a four-year-old kicks me in my groin. I've left Juarez behind, and I'm heading east, through Texas. Surrounded by the Chihuahuan Desert, this is where the borderland becomes an arid, almost never-ending wilderness. This sort of landscape is the landscape you'd see in a horror film just before something really bad happens. You're travelling along this, and there's a puncture, and then stuff really kicks off. It's so remote here, the last thing you'd expect is... ..this. No. No way. Can we turn around? Mm! That is so cold. Ah! It's so windy! This might look like a designer shoe shop next to a highway, but it is, in fact, a piece of modern art, next to a highway... constructed in 2005 at a cost of $120,000. So actually this is an art installation, which I can assume is a rather neat statement about hyper-consumerism located in the middle of wilderness. It's incredibly cool, actually, but, like all art installations, I'm going to look at it, I'm going to appreciate it, I'm going to try and really contemplate the subtleties of it and then I'm going to cross the road, get in the car and have a bun. Eurgh! I'm just going to die out here! How ironic to die in front of a thing mocking contemporary culture. Oh, God! The Prada installation is located just outside of Marfa, 170 miles east of Juarez. Everything's a bit alternative here. There are certainly no chain motels in this town. I'm staying in a sort of marooned desert houseboat. This is the battleship. Oh, I love the battleship! It's got walls! It has walls and it's quite warm. Get in there. Get in there. So, my first night in the desert, complete. Left-hand sleeper, just so you know. Quite tidy. Never touch the right-hand side, there are rules. Um, so, I woke up and I'd managed to turn all the heating off, so I woke up and it was about minus ten, and then, went over here and just made myself a nice pot of drip coffee. And as I was doing that, I looked at this dude again and I just... I kept looking and I just thought... ..I mean, they never did tell me who my father was. Even though it's close to the border, Marfa is a world away from the badlands of drugs and cartels. It's a town built on creativity and it's changed what the borderlands mean to people in these parts. The town centre is full of galleries and craft shops, and you don't get much more artisanal than handmade soap. Hi. Hi, there. Are you Ginger? I am. I'm Sue, nice to see you. Hi, Sue, it's so nice to meet you. Nice to meet you, how's it going? Really good. Is it always this cold outside? Never this cold. I mean, it's really... We got a snap and so I apologise for the weather. I'll tell you what is about to snap, is all of my bones, it's like I'm made of ice right now. This is so wonderful, this place. Welcome to the soap shop. Come on back. Like many people here, Ginger washed her hands of her old life and moved to Marfa in search of a fresh start. I moved here from New York City and I thought, "Oh, I need, like, a small-town hobby," like, and I thought how quaint to make soap. It would be so fun. So, I'm going to let you cut this one. Oh, dear. There you go, now push it through the wire. Now I understand. Takes a while, doesn't it, with me - just takes a while. Oh, this all I want to do for the rest of my life. Oh, it's so soothing. Oh, it's just... Knife through butter, look at that. I'm living in Marfa from now on, forever! So why did you leave NYC? I wanted to get out of the city. I'd gone through a big break-up and I thought, "I'll never date again." That's horrid, isn't it? And I moved here and I met some of my best friends and it's a great community. Did you date again? I did. It's a love story! It doesn't get better than that. I met somebody here. A love story with intense personal hygiene! Yeah. There's something about the landscape here and the vastness of it. You've all got this pioneer spirit. Does it feel like that in Marfa, does it feel like people have come to this wilderness space to get away from things? I like to say we all moved here for a reason... Mm. ..and that's pretty much kind of all you need to say. To see just open space, it gets in to your blood, and you really can't do without this landscape. Having got a feel for soap-cutting, Ginger decides - wrongly - that I'm capable of making a new batch. So that's our coconut oil... This involves melting together coconut, olive and palm oils... This is the palm oil, and how much do we want of that? 60. ..and then - just messing about. What brave new world is this? Isn't this great? But you've not even... Don't you use this in baking? No! We stick an old-fashioned sort of thermometer in there. Oh, this is great. Try it. Oh. Oh, God, I want to check... Can I do it on me? Yeah. It's 69.7. What am I? Measure me! Perfect. 72. 87. My mouth is, like, over ten degrees hotter than my back. The soaps are fragranced with local products such as honey and herbs, and then sold across America for $12 a pop. Night-night. Like a moth to a flame I was drawn to the sign. MUSIC PLAYS INSIDE I love this modern-day frontier town full of pioneers staking a claim. Cowboys side by side with hipsters and creatives. You are everything. You're top cowboy to me. Well, thank you, darling. You're welcome, sweetheart. Can I buy you a drink for that? Yes, please. What would you like? Anything you think is going to put a smile on my face. You want a beer and a shot? Why not! MUSIC PLAYS SUE WHOOPS It makes me wonder what other distinct communities are living along the border. * It's time to head deeper into the great outdoors. So I knew today that we were driving in the wilderness. You could see the remoteness of this landscape. So I thought, "I'll have a really big breakfast." And then I had another breakfast and then I got them to make me some sandwiches, just because you never know... And there's no stops here. And...it's still morning, and I've eaten everything. There's still crisps in there, though. Don't tell anyone. We're driving 100 miles south-east of Marfa, towards a region known as Big Bend. The Big Bend National Park and State Park cover more than one million acres. For hundred of miles, the Rio Grande - literally "big river" - serves as the international boundary. There are no checkpoints, no barbed wire. The epic canyons provide nature's version of the wall. All right, Sue, are you ready to go on the Rio? I certainly am. And what better way to experience life on the liquid border here than canoeing down it with Austin, a local river guide? One, two and three, roll off. Nice. So just grab that handle and we'll go to the river. Do you know what? This is the first time it's properly struck me that... That's Mexico. ..that's Mexico. Oh-ho, we're on the Rio. Happy days. Let's do it. Cool. Already I'm the happiest I've ever been. Oh, I love the Rio! Me, too! This is about as close to perfection as you're going to find... Yeah. ..in this life. We got the first big rapid. Bring it on! Do I paddle or not? No, you're good. It does feel like you're travelling through something properly ancient. Right. You know, this was formed millions of years ago and has remained pretty much untouched since then. Yeah. It's genuinely one of those unspoilt wildernesses, isn't it? Absolutely. Talking of which, this is an incredible canyon. Yeah. So quiet. It's so brilliant to feel this insignificant, isn't it? That's where the calm comes from, just knowing you're just irrelevant in nature. Because of the inaccessible landscape, almost nobody tries to cross the border here, so most people think there's no need for a man-made wall. But with the wall being built elsewhere in Texas, this could change. Webb County, just downstream east of the Big Bend region, they've just got it approved to have a continuous wall in their county. What's that going to do, will people want to stop coming? Absolutely not. They're going to bring them here. People are going to start going to the places that have no wall. People are going to start seeing the Big Bend as a way to traffic through. Yeah. This will become a pinch-point for migrancy. Austin's fear is that if migrants get pushed to Big Bend, demand will follow for a wall to be built here too, in this pristine wilderness. It's my second day in Big Bend. We really are in Texas, I promise. I know it looks like we're in a studio and someone's let a smoke machine off, but I promise, we have come all this way. Today, I'm going on a hike with park ranger Tom. You're looking the full part of ranger, if I may say. Well, how do? Welcome to Big Bend National Park. Well, what a day we've picked for it! It's not every day you get to see the inside of a cloud in West Texas. I know. What a great workplace, though. Your office is incredible. It's definitely a different type of place to live and it's a real special place. What about groceries and schooling and... So, groceries, most typically we go to like, say, Alpine, that's 100 miles away, or Midland-Odessa, that's about five hours away. So, for a pint of milk, it's a ten-hour round-trip. Pretty much, yeah. But the whole culture of the border, along through the wild, remote Big Bend has traditionally been one of essentially non-existent borders, almost like a transparent border, and people living on both sides. In the early days of this part of Texas, you really needed to depend on your neighbours to survive out here in this difficult place. I'm hoping to see one of Tom's famous neighbours today - the black bear. In the early 20th century, the bears disappeared from the region, after excessive hunting. But they've since come back. So, the park was established in 1944. There were no black bears here. None. And then, suddenly, like, in the mid-1980s, there was a big influx in the sightings of bears. Since 1989, we've had this resident population of black bears here, we think there's about 30. A very healthy population. And turns out, by studying the DNA, we found that they did come from Mexico, they came from a population in the big mountains in Mexico, and we think that they're still kind of going back and forth. See, there's no borders for bears. No. But that's the story of human migration too - you go where the food is... Isn't that incredible? ..where the work is, where the happiness, the joy is. Yeah, right. It's just, the bears are still allowed to do it, I guess. For now. Who knows? For now. They depend on that ability to move, and that ensures their survival. Sadly, the bears seem to be hiding from me today. I shan't take it personally. But there is something else to look at. Woo-wee, look at that! Oh-ho! Hello. Nice. Yes! Oh, look, we're above the mist. Oh, yeah, that's cool. That is cool. It just taps in to a completely calm, primitive part of you that just wants to just be in the moment. No wonder the bears come up here. They like the view. As far as nature is concerned, this is one unbroken landscape. Building a wall here is unthinkable. But down the river, that's exactly what is in motion. I'm driving to Mission, East Texas, situated on the banks of the Rio Grande. The river is more accessible here, and in the last year, there have been over 150,000 illegal crossings. Now, plans are under way to build a new 55-mile section of wall. President Trump's vision is becoming a reality here. But one local priest has made headlines for publicly opposing it. No trip to the border would be complete without a visit...to the priest. I won't lie, there's a certain amount of trepidation because it has been approximately 40-plus years since my last confession so, boy, does he have a lot to deal with! Hi, there. Father Roy. Welcome. Thank you, I'm Sue. Good to see you. Sue, nice to see you. I appreciate you coming. Estas en tu casa. Make yourself at home. This is Bendito, this is Charlotte, they're our guardian angels, four-legged guardian angels. Good to see you. Good to see you, nice to have you here. What a stunning church. A beautiful old place. This historic chapel was built in 1865 and the city of Mission was named in honour of it. According to plans, the new wall will block off all access for Father Roy's congregation. You have the natural border, the river, which marks the boundary between Mexico and the US. You have the wall, so, your church is right in the middle of an enforcement zone. Yeah. Who's going to be able to come to the chapel? Yeah, we'd be in a kind of a no-man's land and, of course, they tell us, "Don't worry, it'll work out." I hate to be cynical, I said, "Well, but it's working out for you, you have all the power, "and how's it going to work out for us?" Father Roy's objections to the wall have angered some people. So, this is your boat? This is our old boat, 50-year-old boat. It's a beaut. He wants to show me how this contentious border is affecting life on the river. ENGINE PURRS Off we go. Yeah, there he goes, there he goes. Look at it, isn't it beautiful? Oh, yeah! With so many migrants risking their lives to cross the river here, border patrol is a constant presence making the place feel a bit like a war zone. Look at those guys. That's a Texas Highway Patrol gun boat. There's four machinegun nests on that boat. Yeah, I noticed. Looks like a Vietnam boat, doesn't it? It does. Looks like a gunship. So you said earlier, there were some local people who were angry with you and they were going to... They're not local. That's interesting. They came from somewhere else to build a wall. What? They're building their own wall? They're building their own wall here. It will just run up along this one farm. So is that on their land? That's private land? Yeah, this belongs to a beautiful sugar cane farm. See, now they're digging into the... I don't know what they're doing. Oh, they're actually doing it. It's just some kind of - like a vigilante wall group. These diggers are being paid for by We Build The Wall, a right-wing organisation led by former Trump advisor Steve Bannon, that raises private funds to build their own wall... ..because, apparently, the official one isn't going up fast enough. They're really tearing it up, aren't they? They've just eroded a very important river bank by scooping away all the natural reeds. And there's a lot of little wildlife living up and down here that's going to have to flee. I don't know where they're going to go. And it won't accomplish anything, it really won't even protect this beautiful farm because you can just go down to the east end or go up to the west end of the wall and walk around it. Talk about disheartening. I used to take the dogs walking up in there all the time. I guess you wouldn't be very welcome there now. No, I guess not. Better not try it again. Do you feel threatened by them? A little bit, yeah, a little bit. That's not... Uneasy. Kind of... The idea that... You know, the pastor, the shepherd likes to think that his flock likes him. Let's just experience the river how it should be. ENGINE OFF DISTANT WHIRRING I say that... You can still hear the Border Patrol helicopters out there somewhere. Sweet. If this is not sweet, I don't know what is. That is sweet. But the reality is it's the opposite of that. It's so contested and it's a pollut... It's an emotionally polluted river, is what I'm going to say. Yes, I had never heard anybody say that, but that's a good way to say it. You might even say spiritually polluted. Spiritually polluted. I have to say that I think what I can smell is burnt dog. There's a very strong... I think Wigglet is cooked now. I'll turn her over because she's roasted one side. You're too citified! LAUGHTER A helicopter, a Border Patrol gunship, the happy crusading priest, and a bunch of vigilantes embarked on an act of geological vandalism in an effort to mimic Trump's wall on private land. That's a snapshot of the border right there. * Supporters of the wall point to images like these - tens of thousands of people fleeing Central and South America travelling through Mexico in the hope of finding asylum in the US. They find the border closed to them and have to remain in Mexico, in camps like this one in Matamoros, while their cases are considered. I've come to another church in Mission, to meet a group of volunteers who are helping the migrants in the camp. Sue, how are you? Hi! I'm a little busy, how are you? Patricia. Patricia, nice to see you, hi, everyone. How's it going? This is my wonderful team. This is the chain gang. Yes. Can I help out? Absolutely. We have a chair with your name on it, I think. Perfect. Cathy, there's a new kid in town! LAUGHTER So how many tacos are we going to make today? Between 900 and 1,000. Between 900 and 1,000? Yes. And so, why? What motivates you to do it other than the goodness of your hearts? There are hungry people. There are. And basically because we believe that God has commanded us to feed the hungry and take care of the desolate. But it's still not enough, I mean, they're living in horrible conditions and no matter how much food we bring, it's not enough. That looks like a nice purse. Yeah, I've got the comb, got one in there... These rucksacks are for the children in the camp. What blows my mind is that the US and Mexican governments provide almost no support for the migrant camps. It all falls on the shoulders of well-meaning volunteers. The soft toys are really getting to me because I remember what it was like when I was a kid, and how much comfort I found in just something that was squishy and I could press close to me. And I came from a safe house, where I had a roof over my head and enough to eat. So imagine... imagine how much joy this could give somebody who has nothing. I am so over-invested in each one of these rucksacks. We meet up with more volunteers at the border crossing, and take the food and backpacks over to Matamoros in Mexico. And just the other side, there's a car park full of tents that's now home to over 2,000 refugees, whose chances of gaining asylum and making it into America are very slim indeed. Then you just give one of these. HE SPEAKS IN SPANISH, SUE RESPONDS Hola! Que tal? Salsa? Oh! Taco? No? OK. Thank you. I've seen how the border can bring out the worst in people. But here, it's clear it can also bring out the best. Senor, senor... Caballos? OK. Caballos. You like My Little Pony? Si? That is for you, then. This is so pretty. Show me, show me? Listen, this is important. Never...stop...dreaming. Never stop dreaming. Drea-ming. Dreaming. Dreaming. You sing? Canta? GIRL SINGS It's so much easier to just talk about migration without experiencing it. And all you need to do is imagine one child and populate your imagination with her age, her eye colour, her future aspirations. And then you meet a child and it makes it even more pertinent and even more resonant and even more important that something is done because that's just a baby. That's just a baby who is as brim-full with hope and passion and optimism as I was. It's just that geographical happenstance made me fortunate and made her unlucky, and that's what's so heartbreaking, the lottery of it all, and that's what has to change. It's surprising to see how many people have to come here with their young children. High five! Oh, ppfft! Ooh! I'm as shocked as you are... This family are fleeing violent gangs in Honduras. Tell me about your life in Honduras. Did you have jobs, did you have a house? What was life like? HE SPEAKS SPANISH Were you being bullied, were you being pressured to join a gang? HE SPEAKS SPANISH SHE SPEAKS SPANISH So your choice is, if you're sent back, to either be killed or to become a gang member? Muerto. So lo muerto. Many people think that migrants just come for work, for money. But you guys have left everything, left good jobs, left a lovely home, left your family because your eldest son made a choice not to get involved in crime? * Since the US government introduced the Remain in Mexico policy the success rate of asylum seekers from countries like Honduras has dropped to below 1%. The closer I get to this border, the more I realise this isn't about a wall and it isn't about the United States and Mexico. It's about the bigger picture, it's about the haves and have-nots. It's about the developed, complacent world and the rapidly developing world and the friction between those two spaces. And it asks bigger questions than this border. It asks questions like, how much is enough? And why won't you share? And what is wrong with us that we turn our backs when we see need? SOFT GUITAR MUSIC After 2,000 miles and three weeks on the road, I've got one more day in Mexico... ..and I'm spending it in the border town of Reynosa. MARIACHI MUSIC This is Danna Paola, a local teenager who's preparing for the most important night of her life. She's rehearsing the main dance of her quinceanera, a party to celebrate her 15th birthday and a huge tradition in Mexico. Preparations for tonight's celebration continue at home under the watchful eye of proud parents Victor and Karen. Nice to see you. Hi, how's it going? Hola! Hello. Que tal? Bien, bien. You look great. Gracias. Where's Danna Paola? Over here. Oh. Danna Princess! Hola. How are you? Hola. Buenas dias. Hola. Nice to see you! Nice to see you. Hi. I'm hoping the eyebrows are going to stay exactly like that. You look great. Thanks. This is your big day. SHE SPEAKS SPANISH So do you have any idea now you're sort of entering the realm of adulthood, what you want to do with your life? I never had hair and make-up at any of my birthday parties, which makes me suspect that this do is far from cheap. Can I ask roughly how much a quinceanera like this would cost a family? In pounds, �3,000 to �20,000. When my wife told me we were going to have a girl, I started, you know what, the first thing, it will be the quinceanera. It's that important? It is that important. As the mother today, are you nervous about what's happening? You've managed to get her through all that turbulent, vulnerable period of her life. You should be really proud. This is a young Mexican with all of her life ahead of her, whose future is entirely in Mexico. We have taught her to love Mexico and to study here in Mexico and work here in Mexico. Oh, God, the tears are starting again! I've run out of tissues! The news only tells you of depravity and violence. It doesn't tell you about sweetness or joy or family. The news tells you about the people who want to leave Mexico, but it doesn't tell you about all the people who want to stay. MEXICAN SONG The quinceanera is a little like the love child of a bat mitzvah and debutante ball. Just like a wedding, the father gives his daughter away... ..not to another person, but to the world. SENTIMENTAL MUSIC PLAYS I've just cried three times but there's more on the way. Watching Danna Paola dance with her father, I realise that the common link in everything I've seen on my journey - the good and the bad - has been family. People doing their best for the next generation, whether that's protecting what they already have or providing them with greater opportunities for the future. In this divided part of the world there's a lot that people have in common. What did I know before I came to this place? Well, I knew that the wall was the most contentious structure, pretty much, on the planet. And then I walked along it, and drove along it, and got a boat along it, and what I now understand is the wall is a paradox. The more you see it, the less divided you understand this place is. This is one landmass. It's one continent carved up by colonialism and wars, but its people, the social geography, remains the same. People reach out to one another. They share values, they share passions because here, beyond the headlines of pain and suffering - which do exist - there is also joy and fun
