Plot
Will Atenton, a successful editor for a New York City publishing house, quits his job to focus on writing a book while spending more time with his wife Libby and their young daughters, Trish and Dee Dee. The family is initially happy to live in their Fairfield County "dream house" near the forest. Soon, they grow uneasy because of a series of unsettling events. It all seems to tie to a crime committed in the house five years earlier, when a man named Peter Ward apparently murdered his wife and two children and was committed to a mental hospital from which he has been recently released due to lack of evidence.
Will approaches his neighbor Ann for help, but she is apprehensive, while her estranged husband Jack is outright hostile. Will visits the facility where Peter Ward was housed, and discovers that he is actually Peter Ward.
During the attack that claimed the lives of his wife and daughters, Peter was shot in the head, so he has no memories of the murders. In order to cope with the grief, he fabricated a delusion in which his family is still alive and created a new identity based on his inpatient ID band "W1-1L 8-10-10". Once dismissed, Peter moved back to his abandoned house, which is now condemned, but in Peter's mind, is still unspoiled.
