A friendly face masks the mind of a twisted serial killer in Spanish painter-turned-filmmaker Martin Garrido Barón's disturbing tale of a man who has finally succumbed to his most violent and murderous impulses. Antonio Frau (Fernando Acaso) has just been released from prison after serving 25 years for the murder of his former girlfriend. Upon inheriting a dilapidated motel from an unknown relative, Antonio determines that his sudden good fortune is a sign from God that he is to begin cleansing the world of those tortured souls who have lost the will to carry on. With a driving urge to achieve notoriety, Antonio sets about luring a series of naïve victims to room six for a series of grueling, blood-soaked purification rites which he meticulously documents in a diary of both images and the written word -- all the while hiding his heinous crimes from his unsuspecting new wife.
