Plot[]
Fawn Harriman, a Dannemora high school student whose parents died a year ago, inherits the Roxy, an abandoned theater located in Amityville, New York. Fawn visits the Roxy with her friend Indy, boyfriend Kyle, Kyle's bullied younger brother, Jevan, and Jevan's friend Matt while one of her teachers, Victor Stewart, looks into the history of the theater, as well as Amityville. Fawn and her friends become trapped in the theater, which has no cellphone service, shortly after meeting Wendy, a runaway who has been squatting in the Roxy. After making several unsuccessful attempts at breaking out of the theater, Fawn and the others encounter paranormal phenomena, like an apparition that resembles Fawn and a Ouija board that spells out the word "SISTER."
During the course of his research, Stewart notices that six people always die on every November 13 in Amityville. Stewart brings his findings to Elliot Saunders, the mayor of Amityville, who explains that the caves that are located beneath Amityville are a gateway to Hell that was accidentally unsealed centuries ago by the Shinnecock. The first six Shinnecock who entered the catacombs were possessed by demons, and buried alive in the caverns by the other Shinnecock. The catacombs were at some point unsealed again, and ever since a cult made up of Amityville's elite has sacrificed six people (including every elite's firstborn child) to the demons, to keep them appeased and to stop them from spreading from Amityville to the rest of the Earth. Fawn was supposed to be sacrificed to the demons alongside her twin sister, Adrienne, but her parents only gave the demons Adrienne. The cult orchestrated the deaths of Fawn's parents, knowing that they would try to stop them from "apologizing" to the demons for the Harrimans' earlier transgression by giving them Fawn. Saunders, wracked with guilt over all of the deaths that he has overseen and orchestrated, commits suicide after killing his own bodyguard and giving Stewart a special key that will grant Stewart access to the Roxy.
Stewart saves Matt, but Wendy disappears while Fawn is captured by decomposing demons who have killed and replaced a surveyor, Jevan, Indy, and Kyle. Stewart and Fawn escape from the demons, but just as they reach an exit, Fawn, her voice now demonic, drags Stewart back into the Roxy while yelling, "I'm Adrienne!"
