Based on the blockbuster Warner Bros. Pictures film starring Christian Bale and Heath Ledger.

Allied with both the police department and the district attorney's office, the vigilante known as Batman continues to bring justice and hope to Gotham City.

But one man dares to mock Batman's mission. A man with a twisted sense of humor. A man whose grotesque smile is reflected on the calling card he leaves at the scene of his crimes: The Joker.
