Lila Jones goes to work at Oakdale Mental Hospital with her mom for a year but she doesn't even last a day there. She was told to take care of Harry Styles, one of the most insane patients there but half way through the day things go wrong and he is forcing her to help him escape. He takes her away, out of town and to an abandoned house in the woods. Harry becomes the least of her worries when she realizes something else lives outside the walls of the house and deep in the woods, something evil, something that wants both of them dead.
