A woman recovering from a personal tragedy imprisons a man she met at a party, shutting him in a room of a building demolition.

The young girl, Antónia Margarida Castelo Branco, is handed over by her mother to Brás Telles de Meneses because of the obscure interests between rural aristocratic families in the North. Brás is a ruined man, a bohemian with a reputation for violence and erratic behaviour. Antonia’s fortune is the first sacrifice made by the young wife. Fascinated by the man who humiliates and ill-treats her, she follows him in a pilgrimage to increasingly barren lands, to increasingly less hospitable houses.

The young film student Maria do Mar is working on a documentary about the old manor houses along the Douro River. It is the final project in her thesis on “Reality in Cinema”. Maria has an unlimited confidence in what is visible. Her candour and her naivety allow her to see the bright side of life – such as the beauty of the landscape and the authenticity of the place, or what’s left of it. But when Maria enters the final manor house on her list, she soon realises that something is going on in this house that is not as innocent as it first seemed. The manor is truly a house of horrors.
