Marc, a problem teenager, is bored living in his native, depressing city of Sete. Suddenly, a simple phone call makes him aware of the existence of Stephanie, a sister he has never met. Armed with a pistol his mother had found, he sets out in the search of Stephanie. After stealing five hundred francs from a perfume shop, he is stopped by a policeman who wants to search him. In the car, Marc threatens him with the gun, demanding that the policeman help him find his sister. The often tense relationship between the two travelers is a complex one.
