The Blackcoat's Daughter

Two young women at Bramford Academy, a Catholic boarding school in upstate New York, are left behind over winter break and are assailed by an evil, invisible power when they're stranded. Emma Roberts plays Joan Marsh, while Kiernan Shipka plays Kat. The story is split into three timelines, each with its own dark and supernatural events, including possession, murder, and a possible exorcism.
