Right after his release from prison, Victor (Jean-Paul Belmondo) resumes his con-man activities. He rents apartments he doesn't own, sells nonexistent fighter planes to African countries, and by turns pretends to be a gardener, lawyer, private detective, governmental official, and even a transvestite in order to fool his unsuspecting victims. He does it all under the nose of his charming but naive parole officer Marie-Charlotte (Genevieve Bujold). When Victor finds out that Marie-Charlotte's father curates the museum that has an extremely valuable painting, he and his friends decide to steal it.
