Brian Sutton moves into a new house, with his son Mark. Everything is normal for the first week, then things begin to change for the worse. Brian wakes at 3:13 a.m., to his son carrying on a conversation with an unknown man. Brian rushes to his son's room, worried someone has broken in, but when he checks the room, his son is asleep in bed. Before Brian can figure out what is going on, the door at the end of the hallway opens up, and his son walks out of the bathroom.
