The film consists of three novels. The film begins with the fact that the Bernard Blier hero removes a lantern from the entrance to a brothel. The second part is about how the lantern and jewelery were stolen from a young baroness. And in the third part the hero of Louis de Funes hangs a lantern at the entrance to his house.

After a harrowing breakup, Marcel returns to his favorite hotel to find his room occupied by a journalist, whom he attempts to impress.
