Movies like amnesiac

Amnesiac (released in the United Kingdom as Unconscious) is a 2014 American mystery film directed by Michael Polish and written by Mike Le and Amy Kolquist.

The film begins with a family of three traveling along a highway. The scene ends with a child screaming, and the male protagonist (Wes Bentley) is seen resting in a bed, in a large room, attached to hospital equipment. The female protagonist (Kate Bosworth) visits him dressed in formal business attire, which is a frequently re-occurring theme in the film.

The male protagonist is shown to become suspicious of the female protagonist, who claims to be his wife. When she leaves to conduct errands, the male protagonist explores the house. After leafing through a photo album, he searches the basement where he finds a film projector, medical tools, anatomy charts and books, and a corpse hidden in a cabinet. He confronts the female protagonist when she returns home, who explains that the corpse is her first husband before knocking the man unconscious and drugging him.
