Twenty years after Bruce Wayne retired as Batman, something shady is going on at his old company, now called Wayne-Powers and run by Derek Powers. While Warren McGinnis accepts a disc from his co-worker Harry Tully, Warren's son Terry runs into Jokerz, hoods who style themselves after the real Joker, who pursue Terry up to the gates of Wayne Manor, where Terry gets a hand from Bruce himself. Carrying him inside the mansion, Terry stumbles across the Batcave. Returning home to find his father dead in an apparent robbery, Terry discovers the disc and returns to Wayne Manor for the Batman's help.
