Master of horror John Carpenter (Halloween, The Thing) directs this terrifying battle between humankind and ultimate evil. A group of graduate students and scientists uncover an ancient canister in an abandoned church, but when they open the container, they inadvertently unleash a strange liquid and an evil force on all humanity. As the liquid turns their co-workers into zombies, the remaining members realize they have released the most unspeakable of horrors, Satan himself, thus paving the way for the return of his father—the all-powerful anti-God. Terror mounts as the last two members of the team must fight to save an innocent world from a devilish fury that has festered for over seven million years. © 1987 Universal Studios.
