A new faction of the Jokerz gang—consisting of Bonk, Woof, Ghoul, Chucko and the Dee-Dee twins—attempts to steal high-tech electronic equipment, but they are intercepted by Batman (Terry McGinnis), the protégé of the first Batman, Bruce Wayne. The gang reports back to their leader, revealed to be the Joker, who was Bruce's nemesis and has mysteriously reappeared following his presumed death years ago. The Joker kills Bonk for defiance and to intimidate the other members.
