Heretics, The (Blu-ray)

A notorious cult kidnaps a young girl and sacrifices themselves by the light of the locust moon. The next morning the girl awakes, covered in blood and surround by corpses but safe or so she thinks. Years later, the locust moon is set to rise again and the girl is captured once more by a surviving member of the cult. She is taken to a remote cabin where she learns that a demon has been growing inside of her all these years, and before dawn breaks, it will rise.
