Late at night in a countryside house, Raymond Smilie hears an ominous voice. He reacts by playing his red Flying V loudly in front of a crucifix. His mother enters his room and unplugs the guitar. When Ray awkwardly explains he plays to avoid hearing "Him," she says he needs to return to the mental hospital. Ray continues to hear the voice and kills her. Shortly after, a man enters the house and sees the dead woman.
Some time later, the house is sold to Jesse Hellman, a struggling painter, his wife Astrid and their daughter Zooey. The real estate agent says that the woman who lived there died when she fell down the stairs, and her husband killed himself out of despair. Elsewhere, Ray checks into a motel. He listens to tapes preaching about the Devil, and plays his guitar. When a noise complaint brings a police officer to his room, Ray stops playing.
After settling into the house, Jesse starts hearing the same voices as Ray. Inspired, he paints a black and white painting based on an upside down cross motif. Jesse later approaches Belial, an art gallery whose owner Leonard previously turned away his portfolio. At his insistence, the receptionist looks at the scan of the painting and appears pleased. One evening, Ray shows up and has a brief conversation with Zooey, who tells him she would love to have a Flying V. Ray wants to enter the house, but an angry Jesse turns him away.
The next morning, Zooey and Jesse find Ray's Flying V outside their house, but Jesse refuses to let her keep it. Elsewhere, Ray kidnaps a boy. He carries the boy to a motel room, dismembers his body and puts the chopped up parts in a suitcase. Ray buries the boy in a hole already filled with several suitcases. Meanwhile, Jesse defaces a commissioned butterfly mural he had been working on, transforming it into a new painting with distorted faces of children - including the one Ray killed. Immersed in his work, he forgets to pick up Zooey at school, and to appease her, he lets her keep Ray's guitar. Jesse keeps working on the painting, which depicts the children's heads being devoured by a black creature and adds Zooey being burned alive. He tells a horrified Astrid that he feels the children inside him screaming to be let out.
At night, Ray sneaks into Zooey's bedroom. He covers her mouth and explains that "He" wants her, but Ray is trying to avoid hurting her. Zooey breaks his grip and screams, alerting Astrid and Jesse, but Ray flees. The Hellmans go to the police, who suggest they change the locks.
The next day, Leonard arrives to see Jesse's latest work. Pleased with the painting, Leonard offers to become his patron, with the privileges it brings. Jesse cuts the meeting short in order to rush to pick up Zooey at school, but he gets a flat tire and runs to the school to find Zooey missing. In Ray's motel bathroom, Zooey is tied up with duct tape. Ray tells Zooey that he can no longer resist "Him," and that "He" considers her "the sweetest candy." While Ray prepares to kill her, Zooey frees herself and escapes. The Hellmans are reunited at the police station. The police tell Jesse of Ray's murderous history as a child. Ray had explained that he served the Devil and that the murdered children were "His candy". The Hellmans are escorted home, and two police officers are stationed outside the house, with the intention of placing them under witness protection.
Jesse contemplates in his studio and eventually destroys the mural. Meanwhile, Ray kills the officers and takes a gun from one of them. Ray breaks into the house and shoots Jesse and Astrid. He drags Zooey outside to retrieve a gasoline canister before bringing her to her room, dousing the floor, and setting it on fire. Astrid wakes Jesse up and the two leave the house. Jesse climbs through Zooey's bedroom window and fights Ray, whose eyes glow eerily as he catches on fire. Jesse bludgeons Ray to death with his own guitar.
Jesse gets Zooey outside safely. He is drawn to a spot near the house, where he finds the suitcases with the children's bodies that Ray had buried. As the sun rises, Jesse looks to the sky, smiles, and starts to cry.
