Sheila has just gained her independence from her parents at last. She has a new job and a new flat, but things start to go wrong after the first few days. first the banging,then the heat is really turned up when she becomes the favourite plaything of an evil entity.She is driven half mad by things flying round the room, appliances switching on and off by an unseen hand. raped and cruelly tormented by this evil she struggles to make sense of whats happening to her, and tells Bob the neighbour, but is he all he seems to be. then she is driven from the flat whilst two priests go and exorcise it for her. Is this the end evil gone. For her its the beginning of insanity.
