Plot
n 2005, Katie delivers a box of old videotapes to her pregnant sister Kristi and her husband Daniel, which holds footage of young Katie and Kristi with their mother, Julie, and her boyfriend Dennis. A year later, Kristi and Daniel's house is ransacked[N 1] and the tapes are missing.

In 1988, a young Katie and Kristi are living with their mother Julie and her boyfriend Dennis. Dennis notices that since Kristi's imaginary friend "Tobi" appeared, strange things have been happening around the house. Dennis and Julie attempt to make a sex tape, but are interrupted by an earthquake. The camera shows dust fall from the ceiling and land on an invisible figure in the room. While reviewing the footage, Dennis notices the strange incident. His friend Randy suggests that Dennis place cameras throughout the house. That night, Kristi wakes up and talks to someone off-camera. When Dennis questions her, Kristi tells him it was Tobi.

Dennis and Julie hire a babysitter named Lisa to watch the kids, but she becomes desperate to leave due to several terrifying incidents (all captured on camera). The following night, Kristi tells Tobi they're not friends anymore. Dennis discovers a strange symbol in the girls' closet and finds the same symbol in a book about demonology. When Kristi becomes ill, Julie and Dennis take her to the hospital. Katie is left home with Randy, and they play Bloody Mary in the bathroom. Randy is attacked and discovers a large scratch on his torso. They try to leave the bathroom, but a black figure moves and furniture is violently flung across the room. After Julie and Dennis return, Randy warns that whatever they're dealing with is dangerous. Dennis tells Julie that the symbol he found belonged to a witches' coven that brainwashed girls of child-bearing age into having sons, then forced them to give up their sons;[N 2] they would not remember anything afterward. Julie dismisses his claim.

The demon harms Katie until Kristi agrees to do what it asks. She asks her mother to take them to her grandmother Lois's house in Moorpark, California. After Julie encounters frightening activity herself, she agrees to go to Lois's home. At 1 am, they are awoken by loud disturbances and Julie goes to investigate. When she fails to return, Dennis goes to look for her. He finds occult imagery on the walls, including the symbol from the girls' room, and discovers several women, including Lois, dressed in black. He flees back to the house, with the women in pursuit, and finds Julie's limp body levitating above the ground. Her body is thrown at Dennis, knocking him down the stairs. He hides with Kristi in a closet until the demon leaves.

Dennis and Kristi then walk into the kitchen. In the window, Dennis sees the women outside, circling around a bonfire. They find Katie crying near Julie's body. Dennis approaches Katie, but when he touches her, she unleashes a demonic scream that throws him to the other side of the room, injuring his leg. Lois stands before him, and Dennis's body is violently contorted, killing him. Lois then beckons to Kristi and Katie and tells them to get ready. Before they head upstairs, Kristi calls for Tobi and growling sounds are heard upstairs.
