 1896, Montmartre: the Can-Can, the dance in which the women lift their skirts, is forbidden. Nevertheless Simone has it performed every day in her night club. Her employees use their female charm to let the representatives of law enforcement look the other way - or even attend the shows. But then the young ambitious judge Philippe Forrestier decides to bring this to an end. Will Simone manage to twist him round her little finger, too? Her boyfriend Francois certainly doesn t like to watch her trying.
