The film is the immediate continuation of Un éléphant ça trompe énormément, released the previous year. 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 w600_and_h900_bestv2. The film contains a certain number of allusions to the films of Blake Edwards (the Pink Panther series).
