The evil Dr. Combs has reanimated the dead and turned innocent victims into monsters from beyond! Artificially created vampires and werewolves now prowl the streets of Gotham, and only the combined might of the Man of Steel and the Dark Knight can hope to stop them. But when a rogue vampire named Dimeter and a feral werewolf called Janko decide to join their side against Combs and his legion of the undead, Superman and Batman will have to save themselves and all of Gotham from the creatures of the night! Good thing they've called in Green Arrow and his wooden and silver-tipped arrows for help!
