What happened over the next 28 days have never been explained.

From Michael Bay, the producer of The Texas Chainsaw Massacre, comes the true story of Amityville. In November 1974, a family of six was brutally murdered. Now, a year later, an unsuspecting young couple, George (Ryan Reynolds, Blade: Trinity, The In-Laws) and Kathy Lutz (Melissa George, TV's Alias), and their children move into the house that was the site of the horrific event and is now haunted by a murderous presence. What follows is 28 days of unimaginable terror. With demonic visions of the dead and relentless screams of terror, this is the haunted house story that isn't just a movie - it's real.
