Output: The reclusive Helen invites her friend Anne, a writer, to stay the weekend with her at her familys estate. The large manor, located near a lake in a forest, is overgrown with foliage and has mostly been untouched for an extended period of time. Helen, a translator, has recently returned to her native England after working abroad, and had lost touch with Anne. The two have dinner, start a fire in the hearth, and talk over tea before going to bed. The next morning, Helen stops by a drugstore in town, where the clerk Mr. Burke asks about her friend, Cora Porter; she tells him she is not with her. Back at the manor, Helen and Anne go for a walk through the woods. At the lake, Helen tells Anne that someone drowned themselves there. The two women take a boat out onto the water, which unnerves Helen. En route home, they encounter Brady, a handyman who lives in the stables on the property; Anne comments that he was staring at Helen, and Helen responds by saying he disgusts her. Later, Helen spies on him with binoculars from the house. Helen has continuous trouble sleeping at the house, and hears voices emanating from the attic one night. The following morning, Anne borrows Helens car to drive to town. On the way home, she stops by the lake and smokes a cigarette, where she is confronted by Brady, who introduce himself. He mentions Helens friend Cora, whose photograph Anne recalls seeing in the house. Anne returns to the house where she finds Helen distraught over her absence. She confides in Anne that she is ill, and Anne suggests they return to London, but Helen refuses, and then kisses her. That night, Anne is awoken by moaning noises. She asks Helen if someone else could be living in the house, but Helen dismisses the idea. John arrives at the house to pick up Anne, but Anne insists on staying a few days longer due to Helens fragile emotional state. That night, Helens attention is drawn to an attic door in her bedroom, and she begins to masturbate furiously; simultaneously, Anne goes to investigate a noise coming from the attic, and is startled by a figure who stabs her to death. Hannah, the housekeeper, arrives in the morning, and finds Helen asleep on the couch; Helen asks her not to return for several days, saying she needs solitude. Later at the drugstore, Hannah tells Mr. Burke about the interaction, and recalls that she once saw Cora having sex with Brady in the stables, and has not seen her since. While walking through the woods, Helen is confronted by Brady, who asks her about Annes whereabouts; when he intimates that she murdered Anne and Cora, Helen runs away in a panic. At the house, Annes dead body sits in a chair in Helens bedroom, and Helen is plagued by disembodied voices and other phenomenon. During a rainstorm, John arrives looking for Anne, and enters though an unlocked door. Upstairs, Helen stabs him in the head and neck numerous times, killing him. That night Brady stops by Helens house to confront her about Cora, whose decomposing body he found in the lake. He tells Helen he witnessed her push Cora in, but she cooly denies it. When he threatens to blackmail her, she stabs him repeatedly in the face and the back of the head, killing him. The next morning, Hannah, Burke, and his protege Nick arrive at the house. In the living room, they find Bradys corpse. While searching upstairs, they find Johns body in the hallway, and Helen staring blankly through the window. In the yard, she watches as Brady and Cora embrace.
