On October 9, 2006, Kristi Rey and her husband Daniel are killed by her demon-possessed sister Katie, who then abducts Kristi’s one-year-old son, Hunter. The police are still unable to find Katie and Hunter in November 2011, when Alex Nelson is living in a wealthy suburb of Henderson, Nevada with her father Doug, mother Holly, and little brother Wyatt. Alex records footage with a laptop webcam before Alex and Ben set up cameras all over the house after many strange occurrences, which escalate into several cars parked outside a neighbor’s house, and objects such as chandeliers, kitchen knifes, the family car, and garage doors becoming sentient.Paranormal Activity 4 2012.
The neighbor has a son, Robbie, who stays at the Nelsons’ home while his mother is hospitalized. Wyatt tells Alex about Robbie’s imaginary friend Toby,[3] and Alex finds Robbie in a closet saying “He doesn’t like you watching us”. Wyatt also tells Alex and Ben about meeting “him”, revealing a green symbol on his back identical to an ancient Hittite symbol, one that would prepare a victim for demonic possession. They learn that the possession ritual requires a virgin blood sacrifice. It is then revealed than Robbie’s mother is actually Katie. Wyatt is told by her that he and Robbie were adopted and that his other family needs him back. He argues with an unseen, unheard presence about his real name, declaring, “I’m not Hunter!”. As the month progresses, there are even more odd activities, such as Wyatt going in a trance and levitating Alex. One night, a possessed Katie sneaks into the house and tells Wyatt she’ll wait until he is “ready”. Alex tries to show her parents the footage, but it has been mysteriously erased.
