Bill Crafton, a vengeance-bent hunter searching for the ominous creature that carried off his daughter months before. Into Crafton's stalking grounds come Jack, Carrie, Cindy, Tom and Fred, five young people on a quest of their own. Ultimately trapped in the green hell of Demonwood, Crafton and the youths come face to face with a host of both prime-evil and extraterrestrial horros unlike any imaginable-including bigfoot-like manimal of nightmarish rage, an army of unstoppable zombie slaves and a carnivorous alien terror whose lethal venom induces an excruciating, never-ending torment of death!
