Before the DeFeos moved into 112 Ocean Avenue in Amityville, the house was occupied by the Bronners. In 1966, the Bronner family's eldest son, Franklin, killed his parents and two siblings during Thanksgiving dinner. Franklin, who had a long history of mental illness, claimed to have committed the familicide at the behest of otherworldly forces that resided within the house, and was committed to Danamore State Hospital. Years later, his wife and their young son, Keyes Terry, visited Franklin. Despite being sedated, Franklin killed his wife in front of Keyes. Keyes repressed the memory of visiting Danamore, and never received any kind of notification about his father being discharged from it in 1986.
In 1993, Keyes, now a photographer, lives in an inner city boarding house with his girlfriend, Llanie. The boarding house is owned by Dick Cutler, and its other tenants include a painter named Suki, and a sculptor named Pauli. Franklin tracks down Keyes, and gives him a mirror that he took from the house in Amityville. The mirror is demonic, and it kills Suki and her ex-boyfriend, Raymond. After Franklin is found dead, Keyes begins looking into his past, and realizes that Franklin was his father after visiting Danamore.
The demon in the mirror assumes Suki's form to kill Dick, and then begins tormenting Keyes by turning into Franklin. Keyes gets sucked into the mirror, which brings him to a Hellish version of Danamore where he encounters undead versions of Raymond, Suki, Dick, and Franklin. The demon then returns Keyes to the real world, and makes it clear that it wants Keyes to reenact the massacre of the Bronner family by shooting Llanie, Pauli, and Dick's wife at the boarding house's Thanksgiving art show. Keyes resists the demon's influence and breaks the mirror, prompting his friend Detective Clark to sardonically quip, "Seven years bad luck."
