A group of curious kids get into big trouble when they decide to explore a ramshackle mansion in this horror movie. They believe that the place is empty but too soon they discover it is inhabited by a wicked sorcerer who uses black magic and human sacrifice to try and revive his comatose bride. He is very close to success and only needs a few more sacrifices. How convenient that the hapless teens should arrive at that moment. He sends out his zombies to welcome them and bring them back.
