A young girl inadvertently unleashes a race of ancient monsters while exploring her father's 19th century mansion in this horror remake written by Guillermo del Toro and Matthew Robbins, and directed by newcomer Troy Nixey. Introverted Sally Hurst (Bailee Madison) has just moved in with her father, Alex (Guy Pearce), and his girlfriend, Kim (Katie Holmes), when she realizes that their sprawling estate holds its fair share of secrets. Descending into the depths of the house, Sally gains access to a secret lower level that has lain undisturbed for nearly a century, when the original builder vanished without a trace. When Sally accidentally opens the gateway that kept the creatures locked up tight, she realizes that in order to prevent them from destroying her family she must convince her skeptical father that monsters really exist.
