Newlyweds Bill and Claire Martin move their new family into a new house constructed by Bill himself. Shortly after moving in Bill finds a doll house (modeled after The Amityville Horror) in the shed. He brings it in the house and puts it in the garage. Later that night, Bill notices the fireplace in the house turns on by itself, heating the entire home. He has a hallucination of his daughter Jessica burning to death in the fireplace. The following morning, Claire finds the dollhouse in the garage and suggests giving it to Jessica for her birthday. At her birthday party, Jessica's aunt Marla and uncle Tobias arrive. Jessica is elated over the dollhouse and finds a chest of miniature dolls inside it: her aunt and uncle, however, seem inexplicably nervous regarding the toys.
