In 1977, "The Amityville Horror" book was published and caused a sensation. The subsequent 1979 film adaptation was a surprise box office hit. It was a film that changed everything. It terrified audiences and became a film and story that people continue to return to. Today, it is the quintessential American horror story based on TRUE events. This is the story of the all-American family that moves into their dream house in the all-American town and experiences the most terrifying demonic haunting imaginable. Demon possession, demon attacks, a portal to hell. A situation so dire, even the church couldn't help them. Through archival footage and recreations, the special, produced by 1895 Films, presents the harrowing true story of Robert Defeo, who murdered his entire family in the Amityville house, and the 28 terror-filled days the Lutz family lived in the house.—Anonymous
