A zombie picture which benefits from original twists like burning the undead, creatures' heads blowing apart, and laser rays blasting the living dead.
Description by Image Entertainment:
In an abandoned prison, a doctor has revived executed convicts as the living dead. Teenager Scott Schwartz (A Christmas Story) creates a weapon from a videodisc player's laser and pursues the walking dead, aided by his girlfriend and grandfather (western star Bob Allen). A reporter (Robert Deveau) on the trail of the story is helped by the town librarian, played in her final film role by Zita Johann (Boris Karloff's "The Mummy," "The Sin of Nora Moran"). On the prison island, the zombies attack a security guard and tear him apart as the reporter and teenager venture into the prison caverns for a final showdown.
