Four young people, tired of working life, decide that they can earn money from crime than they can from work. The film follows their training at the first "crime school", as well as their work.
The film is a road movie that follows a middle aged man who gives a young woman a lift. On the car radio, news bulletins warn the population against a recently escaped sadist who is known to prey on young women and children. Lelouch often cuts away from the main story, if only briefly, to parallel events that are not necessarily crucial to the story but illustrate what is suggested by the radio.
A Paris flea market vendor is transformed into a vigilante after his fiancée is murdered by three vicious thugs on a commuter train. As the revenge-minded young man tracks the killers, a veteran police inspector leads a parallel investigation.
