Batman: Dead End (2003)

Life isn't fair. The Joker escapes from Arkham Asylum. Bruce Wayne puts on his Batman suit, mask, and cape, and goes in pursuit. He's soon found the Joker and begins a fight to subdue the red-eyed, sneering villain. Then, suddenly, things take a surprising turn: the Joker becomes the least of Batman's worries. New enemies appear: it's as if he's found himself in another set of comic books. Can he hold his own?
