Amnesiac

The film opens with a family of three driving along a highway, building tension as a child screams. The scene shifts to a hospital-like room, where the man lies in a bed connected to medical equipment. The juxtaposition hints at a life-changing event that binds the characters together.

The woman visits the man in the hospital wearing formal business attire, a recurring theme that signals something ominous. He begins to suspect that she may not be who she claims to be. This moment plants the seeds of distrust that drive the rest of the story.

When the woman leaves to run errands, the man is left alone in the house and starts exploring. He flips through a photo album and notices gaps and inconsistencies about the people there. Suspicions grow as he realizes not everything adds up about his supposed wife.

In the basement, he discovers a film projector, medical tools, anatomy charts, and disturbing books. Behind a cabinet he finds a corpse hidden away, confirming a grisly secret in the house. The atmosphere turns claustrophobic as the evidence mounts.

He confronts the woman with the basement findings, pressing her for explanations. She declares that the corpse is her first husband, then knocks him unconscious and drugs him. The turning point shifts him from curiosity to captivity.

The man is restrained to a bed-like frame and subjected to shock treatment. He makes a halting attempt to subdue her, but is overpowered. Meanwhile, a visiting postman is killed by the woman, whose body is pushed into the basement.

A detective assigns an officer to investigate the missing mailman, triggering an official inquiry. The investigation begins to piece together the disappearances linked to the house.

The woman dismembers the postman downstairs while the female officer arrives and is promptly killed. The investigation intensifies as the male detective becomes involved in the scene.

The male detective conducts his own search of the premises, collecting disturbing clues. Through memory flashes, the man questions the existence of a little girl he has seen in his past.

The woman reveals a little girl named Audrey kept in a cage, claiming she is their daughter. Audrey's appearance escalates the stakes and tragedy of the situation.

Audrey seizes a knife and lunges at the woman. The woman overpowers Audrey, renders her unconscious, and traps her in a bathtub. The danger within the house tightens its grip on everyone.

The detective arrives at the front door, interrupting as the woman prepares to lobotomize the man. She calms the situation by sending the detective away, then attempts to drown Audrey, escalating the peril. The moment shifts the balance of danger.

The man breaks free and uses the lid of a toilet to render his captor unconscious, but collapses on the floor. Audrey manages to escape from the house, leaving the scene in flux.

The man wakes in a hospital bed and is interviewed by the detective. He learns that Audrey is the daughter of Mason Williams and that they kidnapped her for ransom to fund the woman’s fertility treatments. The detective reveals that the other victims were never found, uncovering the full scope of the crime.

Dressed as a nurse, the woman infiltrates the hospital and euthanizes the man, ending the immediate threat but leaving Audrey’s fate and the house’s crimes unresolved. The ending emphasizes the predator’s continuing danger.
