One evening, in the middle of the Irish countryside, a house seems to take on a terrifying life of its own as objects and furniture turn against the inhabitants, killing all but eleven year old Niamh. The police suspect a gang of homicidal vandals, ignoring Niamh when she tells them about the murderous rage of the house. Nat and Lucas Galin take in Niamh and try to provide her with a loving home, but she continues to act withdrawn. It soon becomes clear that Niamh has powers greater than anyone could comprehend, and is herself a frightening force to be reckoned with.
