Newlyweds Sarah and Cory Morgan have decided to take a relaxing holiday with Cory's 7-year-old son, Liam, to try and smooth over some of the problems Liam is having with his new mom. Despite the idyllic location of Cory's isolated and luxurious country house, the family soon realize they have made a mistake in going there. The house brings back too many painful memories of Liam's deceased mother, and the boy reacts angrily, punishing Sarah for trying to take his mother's place. However, the boy's discomfort is soon put aside when they realize that someone has been using the house in their absence. After having a police officer inspect the house and reassure them that there's nothing to worry about, they decides to stay, at least for one night, which proves to be another big mistake. Their unwanted house guests will soon reveal themselves, and the family will find themselves fighting for their lives.
