When strange happenings start to occur during the night, John believes that his family has returned and is trying to contact him – but as events escalate, his mental health worsens, until he nears total psychological collapse. Just when he needs a friend the most, Bobby appears… but things are about to turn deadly, as John finally learns the chilling truth about his family’s deaths.
