Batman must battle former district attorney Harvey Dent, who is now Two-Face and Edward Nygma, The Riddler with help from an amorous psychologist and a young circus acrobat who becomes his sidekick, Robin.

Batman and Robin try to keep their relationship together even as they must stop Mr. Freeze and Poison Ivy from freezing Gotham City.

Having defeated the Joker, Batman now faces the Penguin - a warped and deformed individual who is intent on being accepted into Gotham society. Crooked businessman Max Schreck is coerced into helping him become Mayor of Gotham and they both attempt to expose Batman in a different light. Earlier however, Selina Kyle, Max's secretary, is thrown from the top of a building and is transformed into Catwoman - a mysterious figure who has the same personality disorder as Batman. Batman must attempt to clear his name, all the time deciding just what must be done with the Catwoman.

Gotham City: dark, dangerous, 'protected' only by a mostly corrupt police department. Despite the best efforts of D.A. Harvey Dent and police commissioner Jim Gordon, the city becomes increasingly unsafe...until a Dark Knight arises. We all know criminals are a superstitious, cowardly lot...so his disguise must be able to strike terror into their hearts. He becomes a bat. Enter Vicky Vale, a prize-winning photo journalist who wants to uncover the secret of the mysterious "bat-man". And enter Jack Napier, one-time enforcer for Boss Grissom, horribly disfigured after a firefight in a chemical factory...who, devoid of the last vestiges of sanity, seizes control of Gotham's underworld as the psychotic, unpredictable Clown Prince of Crime...the Joker. Gotham's only hope, it seems, lies in this dark, brooding vigilante. And just how does billionaire playboy Bruce Wayne fit into all of this?
