The documents received were about another doctor who have killed himself after he killed the woman he was cheating on his wife with. Boyle decides to take his wife and son to Boston. While in the city, they move to a home that has been vacant for some time. It sits away from neighbors, and it seems to be rather isolated.
The house, once belonging to the doctor who died, is located in the middle of the woods. The couple believe they are alone until they discover there is something sinister lurking in the shadows. Boyle's son soon becomes friends with a girl who only he can see. The girl gives him warnings about the house and tells him that his family should leave. After a sitter arrives to watch the young boy, mysterious things happen in the home. Boyle and his wife soon enter the basement where they discover the reason why the house has been empty.
