Plagued by endless visions and nightmares, Jenny Adams suspects that, as a child, she was responsible for the brutal murder of her own mother. Leading up to the death, the family were living in the grounds of an asylum, run by Jenny's domineering psychiatrist father Dr Madsen Adams. It was always assumed that one of the inmates was the killer. When Jenny returns to the now abandoned asylum to investigate the past, she encounters former inmates including a priest, a medium and a drug addict. She becomes trapped inside the decaying hulk of the asylum with her terrifying memories and at least one killer.
