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). 　　 　　译文(3): 偶然发现了一张照片，照片中Marthe拥抱了一个穿着格子夹克的陌生人；蒂安·多西变得嫉妒，并想出各种各样的策略来确定情人的身份。
