10 years after an ageing Batman retired, Gotham City has sunk deeper into decadence and lawlessness. Now, when his city needs him most, the Dark Knight returns in a blaze of glory. Joined by Carrie Kelly, a teenaged Robin, Batman takes to the streets to end the threat of the mutant gangs who have overrun the city. But after facing off against his two greatest enemies, the Joker and Two-Face, for the final time, Batman finds himself in mortal combat with his former ally, Superman.
