Jacques Prévot

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.

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.
