Output: Its 1865. In rural England, a young woman named Katherine is in a loveless marriage to an older man, Alexander. They live at the country estate of Alexanders father, Boris. Katherine is forced to maintain a strict schedule and prevented from leaving the house. Boris scolds her for not giving Alexander a son, but Alexanders sexual interest in his wife seems to be limited to watching her naked body. One day, both Boris and Alexander have to leave the estate for separate business matters, leaving Katherine alone with the housemaid named Anna. For the first time in memory, she is free to explore the area to alleviate her boredom. Katherine soon discovers Anna being suspended from the ceiling of an outhouse by the men who work on the land. She is attracted to one of them, Sebastian, and the next day sets herself up to meet him. When Sebastian comes to the house to visit Katherine, they begin an affair. Anna informs the local priest, who attempts to warn Katherine, but she sends him away. When Boris returns home, he is informed of the affair, beats Sebastian and locks him in a stable, and threatens Katherine when she demands his release. Katherine poisons his food, and calmly makes small talk with Anna as he chokes to death in the next room. Anna is terrified into muteness, and Boris is buried without suspicion. Katherine takes over the estate, and she and Sebastian continue their affair openly. One night, while they are asleep in Katherines marital bed, she awakes to realise that Alexander has returned home. After he reveals that he is aware of the infidelity, Katherine summons Sebastian and they start to have sex in front of him. A fight ensues, during which Katherine kills Alexander. The couple bury Alexanders body in the woods and kill his horse. They are not directly accused of the murder, and Sebastian begins to dress and behave as the lord of the manor himself. A woman arrives at the estate with a young boy named Teddy, who she claims is the product of an affair between Alexander and her daughter. Katherine reluctantly shelters the pair. Sebastian, angry at the change in living arrangements, returns to the outhouse. Katherine realises she is pregnant, but is unable to inform Sebastian. She also begins to bond with Teddy. When Teddy disappears after Katherine scolds him, Sebastian finds the boy sitting over a waterfall and rescues him. When he returns Teddy to the house, he admits that he considered pushing him. Katherine dissuades Sebastian from leaving, promising to do anything he wants in return. While Teddys grandmother is asleep, the couple use the opportunity to smother Teddy. Sebastian hides in the woods while Katherine claims that Teddy died in his sleep. The village doctor is skeptical of the story, but while the issue is being discussed, a guiltridden Sebastian returns from the woods and confesses everything. Katherine calmly turns Sebastians confession back on him, and accuses him of committing all the murders with Anna. Her word is taken over his, especially when Anna remains mute. As Sebastian and Anna are taken away by the police, Katherine remains alone in the house with her unborn child.
