Controversial in France for its depiction of an educational system in crisis, this film focuses on a group of boys who are fed up with their overzealous repressive teachers. Colin (Gilbert Pruchon), Caussat (Louis Lefebvre) and fellow classmates are aware that their school is planning a shindig, but they're not of a mind to cooperate. Frustrated by the scolding and punishment doled out by their teachers, the boys come up with a plan to interfere with the event.
