Amityville: The Awakening (2017)

Teenager Belle Walker moves to 112 Ocean Avenue in Amityville, Long Island with her mother Joan, younger sister Juliet, brain-dead twin brother James, and dog Larry. The family's reason for moving there was to be closer to Dr. Ken Milton, a neurologist hoping to treat James, who is on life support after an accident that left him paralyzed. Upon moving in, Juliet tells Belle that James has been talking to her lately. That night, James flatlines, but is mysteriously revived and opens his eyes.

At school, Belle is taunted by her peers over moving into the home, which she learns was the site of a mass murder by Ronald DeFeo Jr. in 1974. In her third-floor bedroom, she discovers blood stains from the murder concealed under the wallpaper. One night, Belle invites acquaintances Terrence—an enthusiast on the Amityville haunting—and Marissa over to watch The Amityville Horror (1979) at the house. At 3:15 am in the middle of the film, the power goes out and the three go into the basement to locate the fuse box, where they are confronted by Joan, who thinks they are intruders.

Dr. Milton, who suspects James may have locked-in syndrome, performs an EEG test on James that shows increased neurological function. During the test, Dr. Milton witnesses an apparition of flies filling the room and attacking him, and leaves the house, shaken. James quickly gains the ability to communicate with the family via an AAC computer system that allows him to type by looking at letters on a screen. Terrence suggests to Belle that James' sudden revival may be a result of possession stemming from the house, and they suspect that a ring on the ground surrounding the house may represent a magic circle. Belle explains her troubled past to Marissa and reveals that James sustained his injuries after falling off a three-story balcony during a fight with a boy who had leaked nude pictures of Belle online. Belle asks James if someone else is inhabiting his body, to which he replies "Yes" and "Help" via his computer. He asks her to kill him, and she shuts off his ventilation machine. Joan enters the room and finds that James is now breathing on his own.

The next day, Belle types “Outside walk” on James’ computer in order to distract her mother and find the Red Room in the basement, which she believes to be the source of James’ power. Larry the dog is found mauled to death in the lake by Juliet, and Belle confronts her mother with the theory that the house is possessing James. Joan reveals to her that after having lost her faith in God following the death of her husband and James’ subsequent accident, she moved the family to the home, hoping to harness the demonic energy there in order to bring James back to life.

That night, as Belle prepares to leave, Joan knocks her unconscious. Belle awakens at 3:15 am, just as her aunt Candice arrives at the house. James rises from his bed, and harnesses the energy from the Red Room, which revitalizes his body. Belle makes her way downstairs as Candice enters the house, but James shoots Candice with a shotgun. Belle retrieves Juliet from her room, but the house locks the doors, preventing them from escaping. Joan is confronted by James in her bedroom and knowing she is facing death, she retrieves her crucifix, and holds it toward James, but he is unaffected. He reminds her that with the loss of her faith, God is not able to save her. James shoots Joan in the chest before throwing her on her bed and shooting her in the head. He lures Juliet to the third floor, where he attempts to kill her, but is stopped by Belle, who tackles him, resulting in them both falling from the window. Belle lands on top of James which incapacitates him. She drags James outside the circle, after which his body withers back to its paralyzed form, and he dies after thanking her for freeing him from the possession.

A newsreel epilogue reveals that Belle is being questioned for the murders of her mother, aunt, and brother. However, Juliet corroborates Belle's story that James was the murderer. James' fingerprints were discovered on the murder weapon, but Dr. Milton refutes the claim due to James’ paralysis. The news report comments on yet another tragedy occurring in the Amityville house.
