A bigfoot is wounded by a shotgun blast. It exacts revenge, then tries to escape. It loses too much blood and collapses in deep woods, where it is found by high school senior Marcy Dillon. Marcy befriends it and decides to help it elude a posse gathered to capture or kill it. What results is a pulse-pounding, white-knuckle chase onto a deadly mountain, where both their lives hang in the balance.
