Olivier, a handsome but inexperienced and moody young student, meets an actress during a theater rehearsal and is introduced to her social circle of wealthy, jaded friends who enjoy causing chaos on the Riviera by harassing people, throwing extravagant parties, and keeping up with current trends. After being pursued by Elke, he leaves the actress behind and joins the group for a wild party on a yacht. But, his lack of experience and Elke's promiscuous behavior do not mix well. When Charlie accidentally sets the yacht on fire, the group seeks revenge by tricking Olivier into participating in a dangerous bravado contest at a construction site.
