Synopsis: St. Mark's Catholic School for Girls is closed and abandoned after a young student suddenly disappears without a trace. But after 13 years, the school is reopened under the helm of a domineering headmistress (Amy Ciupak LaLonde) and a troubled priest with a past (Ron Perlman). Now, five new rebellious students find themselves trapped in a school that is hell-bent on their redemption. When the girls unite their supernatural skills in an attempt to escape, they realize they must fight for their lives against the ancient and evil demon that holds thrall over the school.
