Argenteuil, July 1973. Five unstable, insecure buddies pass the boredom by pilfering in the stores and revving up their motorcycles. On the eve of July 14th, during a trip to Bastille, a motorcycle paradise, one of them, Roger, gets into a fight with a policeman and is wounded. While fleeing, he meets a young "runaway" who helps him escape the search and rejoin Anne, "his wife". Despite a rather incredible maneuver, the two boys break into an apartment and kidnap the occupants. Anne and Roger don't manage to reach each other "discreetly", and the adventure ends stupidly: surrounded by the police, Roger makes a false move and throws the motorcycle into the ditch. When they get out of hospital or prison, life starts all over again.

This sex comedy concerns the efforts of Julien to get his timid, "backward" 20-year-old son to take an interest in sex and get married. After a series of adventures with women (arranged by papa), Valentin finally gets married to a woman who appears to be as shy as he is. Things get complicated when his father begins an affair with her.

In this gentle comedy, a disaffected group of young people bungle their first hold-up when the old lady they choose to rob turns out to be even poorer than they are. Not only that, but her husband has died, and she needs to get his body back to his hometown for burial and she is getting no help from the state. The would-be robbers good-naturedly agree to help her, and have a series of odd adventures involving the old lady, the corpse, and themselves. Eventually, the old lady dies as well, and they are really in a pickle.
