Ver Cuevana. A young girl, Christiane, leaves her family to join friends with whom she intends to "make a life". Two boys, Jo and Paul, look after the heroine, whose relations seem rather shady. Jo, a guide in a tourist agency specializing in nightlife in Paris, has a "shadow" of his own in the scatterbrained Annette, who is determined to marry him. While touring the capital's cabarets, Jo meets a model, Jacynthe, and her photographer, Daniel, as well as a star, Jackie, and her manager, Helios. The latter organizes a mock jewel robbery for publicity purposes, with Jackie as the victim. But contrary to expectations, the robbery takes place.
