Plot of Paranormal Activity 4 (2012)

The film takes place five years after Paranormal Activity 2, which ended with Katie abducting baby Hunter. Alex (Kathryn Newton) films her younger brother Wyatt's football match. At Alex's house her boyfriend Ben (Matt Shively) arrives later in the evening Alex shows Ben her treehouse in the garden and they discover Robbie, the neighbours child in the tree house. Puzzled with why he is here she takes him back to his own house across the road. In the early house of the next morning Alex hears an ambulance outside at Robbie's house. The next day Robbie turns up to the house after Alex's mom offered to look after him for a few days because his mother went into hospital. Later on the day Alex finds Wyatt and Robbie in her treehouse talking to Robbie's invisible friend. In the evening Wyatt is playing multi-player on the Kinect by himself with Robbie sat on the sofa. Ben asks who Wyatt is playing with and Robbie tells him its his friend. Ben is confused at how Wyatt is playing with no one but the game continues to play. When Alex arrives in the lounge Ben turns the lights off in the lounge and shows Wyatt through the camera the infra-red tracking dots who is impressed. As Alex, Ben and Wyatt dance in the dark and Robbie sits on the sofa, the camera picks up something moving on the sofa next to Robbie. The next day Ben shows Alex that his computer automatically records their webcam chats and in the middle of the night while Alex was sleeping, Robbie came in and slept next to her. He suggests that he can set up laptops around the house to record anything else that is unusual. Over the next couple of days strange occurrences happen around the house, such as Robbie waking up in the middle of the night and talking to the TV, Robbie and Wyatt running around the house in the early hours of the morning chasing a silhouette of a small child figure. Robbie draws a strange symbol on Wyatt's back which Alex later finds to be part of an old cult (and which first appeared in Paranormal Activity 3). When alone in the house Alex hears noises and follows them to the hallway where the chandelier falls down from the ceiling and smashes into the floor. Her father later blames this on the people who fit the lights, but Alex is suspicious of Robbie. The next day she sees from her bedroom window that Robbie and Wyatt have ran across to his house. Alex follows them to discover that Robbie's mother is actually home, who is Katie (Katie Featherston). After Alex takes Wyatt back home he tells her that Katie told him he was adopted like Robbie. Alex questions her parents about Wyatt's real parents but they refuse to say anything. Wyatt later on then talks to an invisible figure, we only hear Wyatt's responses but Wyatt says that his name isn't Hunter. Later, while he is taking a bath, Wyatt is dragged underwater only to resurface with a blank expression on his face. He then insists that his name is Hunter, not Wyatt. At several points, Katie sneaks into the house to talk to Hunter, telling him she'll be with him until he's "ready." Alex's parents go out for the evening and after hearing strange noises in the house the garage door opens. She enters the garage only for the door to suddenly shut and the car to start up, which produces gases in the garage. To escape from suffocating Alex breaks into the car and reverses out of the garage. In the evening Wyatt appears in Katie's room and Alex is picked up into the air. The next day when Alex's mother is downstairs alone in the house and starts to hear strange noises. Katie appears in the house and heads unknowingly to Alex's mother upstairs. When Alex's mother enters the lounge she stands still as something breaths over her. Straight after wards an unseen entity suddenly picks her up and throws her around before dropping her with a final smack onto the floor, killing her instantly. Katie comes back downstairs and drags her body off screen. Some time later Ben arrives at the house to discover no one is home. In Alex's bedroom he goes to view the footage recorded on her laptop before Katie appears behind him and snaps his neck and drags his body into her cupboard. Katie finds Wyatt in the house and tells him that he is Hunter.
