Synopsis: In the aftermath of a personal tragedy, Harper retreats alone to the beautiful English countryside, hoping to find a place to heal. But someone — or something — from the surrounding woods appears to be stalking her, and what begins as simmering dread becomes a fully-formed nightmare, inhabited by her darkest memories and fears.
