Once a year the fair comes for one day to the little town 'Sainte-Severe-sur-Indre'. All inhabitants are scoffing at Francois, the postman, what he seems not to recognize. The rising of the flagstaff under his direction nearly leads into a catastrophe - but everybody tells him, how important his work is. Sneering up Francois continues in the evening of the festive day. Made drunk, some 'friends' persuade him to watch a short-movie in a tent.
