In December 1975 George and Kathy Lutz move together with their three children in an elegant house on Long Island. What we do know is that the house was the site of a horrible mass murder a year earlier. They decide to keep the house and trying to keep fear in the past, but now they are pursued by a murderous presence. That is until George begins to act strangely, and his daughter Chelsea starting to see people. What follows is 28 days of pure unbridled terror of the family of the demonic visions of the dead. Based on the true story of George and Kathy Lutz, The Amityville Horror remains one of the most horrifying haunted house stories ever told because it really happened.
