Raiders of the Living Dead

In an abandoned prison, a doctor revived executed convicts as the living dead. Jonathan (Scott Schwartz), a teenager, creates a weapon from a LaserDisc player's laser and pursues the walking dead, aided by his girlfriend and grandfather. A reporter on the trail of the story is helped by the town librarian. 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.
