To inherit his uncle's immense fortune, Frédéric must divorce his wife with of course all the wrongs against her. He unsuccessfully tries the "love strike" and ends up employing a detective to help him find the fault of his decidedly too embarrassing wife. An idea comes to him: his wife is a fan of naturism.

Having lost his physician's license, Dr. Louis Krantz joins a gang of hoods to treat their wounded. When his son falls ill and needs expensive medical help, Louis decides to participate in a hold-up with the gang. Unfortunately for them, the robbery goes wrong. The gang boss, persuaded that Louis has betrayed them, decides to gun him down.
