Two female students (Kiernan Shipka and Lucy Boynton) are haunted by devilish forces while stranded at their Catholic prep school over winter break. Meanwhile, a mysterious hospital escapee (Emma Roberts) charts a course toward the school, and ends up getting a ride from a grieving, middle-aged couple (James Remar and Lauren Holly). Oz Perkins made his directorial debut with this horror feature, which received its world premiere at the 2015 Toronto International Film Festival.
