Linda, an American choreographer in Paris, is looking for an original birthday gift for her husband, Jean. She organizes a fake audition for an erotic dance show that will never take place in order to use young dancers to fulfill her own fantasies as well as John's. While they are choosing dancers they are fulfilling their fantasies. Three dancers attract her attention: the young couple Daniel and Laure, and their friend Sophie. She seduces Daniel and pushes Sophie into the arms of her husband and destines Laure to the final surprise. But Laure soon understands the aim of these rehearsals and prefers to leave the class. Indeed she refuses to be a gift offered to Jean, while she just thought to come and dance to entertain.
25:52 - During the erotic dance audition, Linda tells Daniel to do some sexual things with Sophie, like lick her boobs. Laure, Daniel's wife, is in the audience. When Sophie comes with Daniel to his place later that day, they fuck for real.
41:37 - Linda fucks Daniel in the dance studio while Jean, her husband, films them through a one-way mirror.
1:02:53 - Linda, Daniel and Sophie do an erotic naked dance, a threesome of sort, in front of Jean, who leaves in the middle of it to go to Laure's place.
1:24:25 - Laure fucks Jean. I guess this could be her revenge cheating against Daniel, while this is the gift that Jean gets for his birthday.
