Three months later, teenagers Zoe and Jeff arrive at the house ahead of their parents, who are moving back to the United States after years abroad. Jeff quickly befriends dog walker April and accompanies her home, where the dog she is watching escapes into the woods behind their neighborhood. It stumbles upon the zombies that had initially escaped the set, and which have been living in the wilderness ever since. The zombies kill the dog, leave it for Jeff and Zoe to find, and follow the pair back to the neighborhood.That afternoon, a man named Joshua Daniels comes to their front door looking for the television set, claiming that he bought it at a yard sale and mailed it to the Paranormal Institute after it killed his wife. Jeff turns him away, but later that night discovers the television set, which has mysteriously migrated to the attic. A bizarre woman briefly appears on the set, beckoning to Jeff, before a man appears and kills her, revealing her to be a zombie. The man, who calls himself The Garbage Man, says that the only way to prevent more zombies from coming from the set is to tape a mirror to it. ........
