Having fortuitously discovered a photograph in which Marthe embraces someone unknown, clothed with a chequed jacket, Étienne Dorsay becomes jealous, and imagines various stratagems to identify the lover. In the meantime, Étienne and his friends acquire a weekend house for a very low price. As in the previous work, the film is largely narrated by the character Étienne, whose tone shifts with the reality of the images. The film contains a certain number of allusions to the films of Blake Edwards (the Pink Panther series).

A hapless orchestra player becomes an unwitting pawn of rival factions within the French secret service after he is chosen as a decoy by being identified as a super secret agent.
