In a provincial town, not far away from the train station, not too far from the big city of Paris, exists a nightclub where small town tastes are challenged by sexually ambiguous performers who tease and agitate conservative thinkers... Jean Marie and Nicole--a faithful couple for over 15 years--are the respectable owners of a dry-cleaning establishment in a small French town who decide to take a break from their weekly routine to visit this local gay night club. To their surprise, they both become entranced by the slinky sexuality of a transvestite brother-sister act. A chance encounter between the two couples sets the tone for a high-risk journey into sexual experimentation. Nicole and Jean begin a new life, dry-cleaning during the day and spinning out of control at night. At first, they let themselves be taken in by the excitement of the game, however later it has dire consequences for the couple's sanity, as feelings are ignited that they both cannot understand.
