Madness had always existed in this house. The Thummel house. Where Abbie Syfert is being driven to watch the Thummel's two young children. Where Kayne and Kaleigh are stored in cryogenic tanks, placed there by their father because he thought they had died. Where one night a year, an unsuspecting child is lured to be sacrificed to appease the dark power the Thummels had called upon decades ago. Where the children's spirits are released from their captive bodies and possess their parents. Where, through their parents, the children do the killing. Where no one escapes Will Abbie?
