When Joe Rodman, retired apple farmer, removes the contents of the graves in the earthen floor of his old Pennsylvania farmhouse, he unwittingly unleashes the spirits of the evil half wolf, half human creatures that were birthed and buried there by Jenna Jerrel, a young incest victim who'd inhabited the house in the late 1800s. When Joe moved into the farmhouse, he'd put the crude tombstones, one reading "Nunny," the other, "Cecil," into a basement closet. Now that his recently divorced, emotionally fragile daughter, Denise, and her two children, Amy and Adam, are moving to the farm, Joe decides to remove the contents of the graves-a mistake that will cost him everything he holds dear.
