Horror set in 1965. Heather (Agnes Bruckner) is a teenage girl whose father (Bruce Campbell) and mother take little interest in her. Heather's parents enroll her in a private boarding school for girls located deep in a remote forest. Heather isn't happy with this turn of events, and she doesn't get along well with her classmates or the head mistress, Ms. Traverse (Patricia Clarkson). As she struggles to make the best of her situation, Heather notices that slowly but surely the other students at the school have been vanishing. There seems to be a mysterious force in the nearby woods which has been claiming the lives of the young women - and will soon be coming after Heather.
