Set in Paris the story follows Lisa, who, while on vacation with her husband, rekindles a passionate affair with her ex-boyfriend. But that may lead to a murder.
Lisa and her older husband, the accomplished CEO-type, go to a resort for a vacation. She finds that her ex-boyfriend is working there and reunites with him. They have some highly turbulent past, like having their friend O.D. on them and they couldn't take him to the hospital and they tried to dispose of his body or something. Anyway, they reconcile and have sex on the beach (41:40). It's a dark and brief scene. Later in Geneve, they have sex again in a hotel room (51:36). The scene is a bit brighter this time. Their sex scene when they were still a couple in the first 15 minutes of the film is shot better, but not by much.
