Story of O is a Franco-German film directed by Just Jaeckin, released in 1975. The screenplay is an adaptation of the erotic novel Story of O published in 1954 by Pauline Réage. A young woman fashion photographer known only as 'O' (Corinne Cléry) is taken by her lover René (Udo Kier) to Château Roissy, where she is subject to various sexual sado-masochistic rituals. She leaves wearing a ring as a sign of her initiation. O meets a model called Jacqueline whilst René introduces O to Sir Stephen H (Anthony Steel), who was raised as René's brother, and the two men share O. Jacqueline moves into O's flat, and is seduced by her. O is then sent by Sir Stephen to the country house of Anne-Marie (Christiane Minazzoli) where she and other young women are prepared to be branded by Sir Stephen. O's visit concludes with Sir Stephen's inserting rings into her labia and being branded with his initials. Sir Stephen then shares her with two other men, the commander (Gabriel Cattand) and Ivan (Alain Noury). Later Sir Stephen, O, Jacqueline and René visit the commander's home in Brittany for a party and O takes Jacqueline to Roissy.
