It's the World's Finest team! Well, sort of. Bruce Wayne's been kidnapped by the Mad Hatter, who's using Wayne as a bargaining chip for Batman's cowl. Since Wayne and the Dark Knight are one and the same, Superman comes to Gotham and teams up with none other than Batgirl!
Superman helps Nightwing and Batgirl stop the Mad Hatter who has held Bruce Wayne hostage and hypnotized Robin and the entire Gotham City Police Department.
