Jean-Claude and Pierrot are young men who travel around France, committing petty crimes and running from the law. After they get in trouble with a hairdresser in Valence, Drôme for stealing his car, they grab his pistol and kidnap his assistant Marie-Ange, an apathetic girl. When they are bored with unorgasmic Marie-Ange, they decide to find a passionate woman and meet Jeanne Pirolle, a woman in her forties who is just released from prison and had spent ten years in a cell. After a threesome, Jeanne commits suicide and the men return to Marie-Ange. They find Jeanne's son Jacques who had been incarcerated as well. Then, the four consider founding a crime family but at their first crime, an attempted robbery, Jacques commits a revenge killing and the others flee. While on the run, they meet a family having a picnic near Col d'Izoard and the delinquent teenage daughter Jacqueline wants to join them. They take Jacqueline and on learning that she is still a virgin, they decide to deflower her. After dropping Jacqueline, the three ride away aimlessly.
