Swimming Pool

Plot synopsis:
Sarah Morton, a middle-aged English mystery author, who has written a successful series of detective novels, is having writer's block that is impeding her next book. Sarah's publisher, John Bosload, offers her his country house near Lacoste, France for some rest and relaxation. Sarah takes him up on the offer, hinting that she hopes John may come and visit as well. After becoming comfortable with the run of the spacious, sun-filled house, and meeting the groundskeeper Marcel, Sarah's quietude is disrupted by a young woman claiming to be the publisher's daughter, Julie. She shows up late one night explaining that she's taking time off from work herself. She eventually tells Sarah that her mother used to be Bosload's mistress, but that he would not leave his family.
Julie's sex life consists of one-night stands with various oafish men, and a competition of personalities develops between the two women. At first, Sarah regards Julie as a distraction from her writing. She uses earplugs to allow her to sleep during Julie's noisy nighttime adventures, although she nonetheless has a voyeuristic fascination with them. Later she abandons the earplugs during one of Julie's trysts, beginning to envy Julie's lifestyle. Sarah sneaks into Julie's room and steals her diary, using it in the new novel she's working on. The competition comes to the fore when a local waiter, Franck, is involved. Julie wants him but he appears to prefer the more mature Sarah, having struck up a relationship with her during her frequent lunches at the bistro.
An unexpected tragedy occurs after a night of flirting among the three. After swimming together in the pool, Franck refuses to allow Julie to continue performing oral sex on him, once Sarah, who watches them from the balcony, throws a rock into the water. Franck feels frightened and tells Julie he is leaving. The next day, Franck is missing. While investigating Franck's disappearance, Sarah learns that Julie's mother died years earlier, though Julie had spoken of her mother as if she were alive. She returns to the villa, where a confused Julie thinks that Sarah is her mother and has a breakdown. Julie eventually recovers and confesses that Franck is dead because she repeatedly hit him over the head with a rock as he tried to leave her at the pool. His body is in one of the sheds.
When Marcel becomes suspicious of the mound of fresh soil where Sarah and Julie have buried Franck's body, Sarah seduces the elderly gardener to distract him. Julie leaves, thanking Sarah for her help and leaving her the manuscript of an unpublished novel written by her late mother, which she had previously claimed that John made her mother burn. Sarah uses the mother's manuscript in her novel-in-progress.
Sarah returns to England and visits John at his publishing office with her new novel. His daughter Julia also shows up just as Sarah is leaving, but is revealed to be a completely different person than the girl Julie that the viewer was introduced to as John's daughter. The viewer now must question whether the story that took place at the country house was a fictional plot dreamed up by Sarah.
