Richard Lafargue is an eminent plastic surgeon haunted by dirty secrets. He has an operating theatre in the basement of his chateau and keeps his partner Eve imprisoned in her bedroom, a room he has equipped with an intercom and 300-watt speakers through which he bellows orders. Eve is only allowed out to be paraded at cocktail parties and on the last Sunday of each month, when the couple visit a young woman in a mental asylum. Following these outings, Lafargue humiliates Eve by forcing her to perform lewd sexual acts with strangers while he watches through a one-way mirror.
