Attempting to live a Norman Rockwell life in the secluded woods of upstate New York, David Poe, a Lutheran minister (Adrian Pasdar of HEROES), and his wife Clare, a child psychologist (Cady McClain), use a video camera to document a growing evil inside their house. Is the house possessed and invading the minds of their twin children? Or is there something else wrong with ten-year old Jack and Emily Poe? The children become distant and secretive, performing cruel and deadly actions on the family pets. Clare tries her best to analyze her children while David uses the faith of his religion to fight back. What starts as a perfect American family slowly begins to deteriorate into a living hell. As tragic events begin to escalate, the lives of the family are thrown into a nightmare of survival. The only question is: who will survive?
