Following the death of her maternal grandfather, 16-year-old Allison, and her mother moved back to the family farm in rural West Virginia. When they arrive on the isolated mountain homestead, old memories, suppressed for a decade, surface, and Allison realizes reality isn't what she'd been raised to believe it to be. It soon becomes clear to Allison that their return to the farm is far from a random event and that, in the end, she will once more have to confront what hides behind the door in the basement.
