1The Others Are we really all alone in the universe? It seems hard to believe that only Earth is populated, but when most of us think of aliens, little green men seem equally far-fetched. Well as 20/20's Pete Cronshaw discovers, there are plenty of Kiwis who say they've had contact with beings not of this planet. You'll meet one man, who after losing time for a number of years, discovers under hypnosis that he could have been abducted by aliens and another who believes he's seen an alien ship, and a group of ordinary New Zealanders who devote their spare time to the worship of extraterrestrial beings.

2Diary of a Soldier In every war, soldiers find a way to record what's really going on, whether it's by diary, or now in Afghanistan and Iraq, by video. But as 20/20 reveals what they have to say, is not what the Pentagon wants you to know. They tell in their own words why some of them think the war's become a joke, and their chilling insights into what's really going on, on the frontline.

3Triple the Love When Hugh Hefner does it it spawns a hit TV series. But ordinary couples say they're automatically classed as sex fiends, when they invite others into their marriage. 20/20 talks to several families about why they believe it's healthier for everyone to live in polygamous relationships, and what they get out of it. As several of the women say it's not always about being attracted to someone else's husband that seals the deal - but a chance to have a meaningful friendship and sisterhood with the other wives.

4Life Without Pain Gabby seems like any typical seven-year old girl who loves playing board games, idolises her older sister, and dancing, but she has an incredible medical condition that forces her to wear a helmet and goggles. She literally can't feel pain, which leaves her at constant risk of serious injury without knowing it. Her parents say they've spent her whole life worrying about knocks and bruises that other people wouldn't give a second thought. But as 20/20 discovers there's hope, when we uncover a woman who's made it to adulthood, despite suffering the same condition.

5They call him Jimmy Justice - a renegade who takes on officials armed with a camera and points out the bad behaviour that they ticket other people for. No cop or traffic warden is immune, any illegal u-turn is fodder for his constant stream of blogging. But is he really performing a public duty or just being a dangerous renegade?
