Taking the Living Dead franchise another step further, this campy sequel finds the survivors of the Necropolis reviving bad habits and snooping around Uncle Charles's experiments. When they uncover a container filled with a substance called Trioxyn-5, they assume it must be safe and start selling it as a party drug. But when a Halloween rave transforms hundreds of Trioxyn-5 users into flesh-eating zombies, the scene gets way out of hand.
