Marilyn Jess goes on holiday to St Tropez with her friend Mika Barthel. They meet a group of people making a porn film and Marilyn gets filmed having sex in the changing rooms of a tennsi club and at a party, among other places. Cathy Ménard plays a porn actress, seen only in the first scene buried up to her neck in the sand and giving head to Olinka and Jean-Pierre Armand while being filmed by Alban. The blonde on the boat is probably Veronica Celes. Every so often Marilyn phones her parents and is groped while doing so. On her return to Paris, she walks in on her father just after he had been watching the porn film that was shot and recognised his daughter taking part.
