George & Kathy Lutz and Kathy's 3 children are moving into an elegant Long Island home. What they don't know is that 6 gruesome murders were committed there the year before - Ronald DeFeo Jr., the oldest son in the family, murdered his parents, his 2 brothers & 2 sisters by shooting them with a .35 caliber in November of 1974. No sooner are the Lutzes moved into the house than they begin seeing horrible things - the ghost of Jodie DeFeo, horribly disfigured bodies - and hearing ghostly voices throughout the house. George seems to notice it the most, and it isn't long before he becomes a danger to those around him. When the local priest, called in to bless the house, comes charging out in horror after being swarmed by flies, he issues a dire warning to Kathy - 'Leave that house'. But will they be able to escape before the house and its vengeful spirits take control of George - and make him into a deadly menace?

On November 13, 1974, Suffolk County Police received a frantic phone call that led them to 112 Ocean Avenue in Amityville, Long Island. Inside the large Dutch Colonial house, they discovered a horrific crime scene that shattered the landscape of the typically peaceful community: an entire family had been slaughtered in their beds. In the days that followed, Ronald DeFeo, Jr., confessed to methodically shooting his parents and four siblings with a rifle while they slept, claiming 'voices' in the house drove him to commit the grisly murders.

One year later, George (Ryan Reynolds) and Kathy Lutz (Melissa George) and their children moved into the house thinking they'd found their dream home. But shortly after settling in, bizarre and unexplainable events began to occur -- nightmarish visions and haunting voices from an evil presence still lurking within the house.

Confused and frightened by her daughter Chelsea's cryptic interaction with an imaginary friend named Jodie, Kathy struggles to hold her family together as George's increasingly strange behavior finds him spending days and nights in the basement of the house, where he soon discovers a passageway to a mysterious and gruesome 'Red Room.' With lucid visions and evil voices swirling through George's head, the house comes alive in a terrifying climax that finds him carrying out the spine-chilling events that would become forever known as The Amityville Horror.

Based on the true story of George and Kathy Lutz, The Amityville Horror remains one of the most terrifying stories ever because of one small fact -- it actually happened. 28 days after moving in, the Lutz family abandoned the residence, lucky to escape with their lives. Now 30 years after the shocking events that inspired a best selling novel and one of the most popular horror films of all time, come revisit the house that started it all: The Amityville Horror.
