In September 2006, Jay Yaple moves his family into a late 18th century house in Enfield, Connecticut. His wife Elka senses something odd about the house. It is not until seven months later, the hauntings begin to happen. Jay and Elka hear scratching notices in the walls; Jay suspecting it's neighborhood kids but can't see anyone near the house. Several nights later, the couple wakes up to hear a static noise in their baby monitors and a female voice suddenly comes out saying "You all are going to die". Their twin girls begin communicating with an "imaginary friend" who they call Casey. After more incidents, Jay does research at the town hall and comes across a long history of murders, suicides, and accidental deaths have occurred in the house. He first invites a non-profit group of paranormal investigators to help them. One of them gets possessed and another is thrown against a wall. Later on, Jay wakes up to find "Casey" sucking the life out of him which then turns into an animal-like creature. Jay eventually calls a bishop who successfully cleanses the house, returning it to a peaceful state. The demon however returns, but the Yaples are stuck in the house until they can sell it.
