The film opens twenty years ago. Six-year-old Ren's screams in the middle of the night bringing her father Rob into the room. She tells him there is a monster in the closet. Rob's reaction isn't that of a normal father, he begins chanting an incantation to keep his daughter safe whilst pulling a gun out inscribed with strange insignia. Ren watches in horror as whatever is in the closet emerges and kills her father right in front of her.
