La Piscine

Jane Birkin stars alongside Alain Delon, Romy Schneider, and Maurice Ronet as a quartet of tanned, toned, beautiful people who spend their summer swimming, lounging poolside, and trysting with one another amid the crystal-blue waters of the Côte d'Azur. But jealousy and a creeping sense of unease gradually infect their languorous idyll -- erupting one evening with a shocking act of violence.
