Romy Schneider and Alain Delon—one of cinema's most potent real-life couples—sizzle and scheme in this deliciously sun-soaked thriller set around a Riviera swimming pool. Their idyllic holiday is disrupted when Delon's friend Harry (Maurice Ronet) arrives with his young girlfriend (Jane Birkin) in tow, and old jealousies and desires rise dangerously to the surface. Jacques Deray's La Piscine is a masterwork of erotic tension and psychological menace, its languid atmosphere masking a story of betrayal and murder that builds to a devastating conclusion.
