Quick recap
In a grim future, Bruce Wayne is 55 and hasn't worn the cowl in ten years. Gotham is overrun by the Mutants, a violent gang. He returns as Batman, rescues young Carrie Kelley, who becomes the new Robin, and beats the Mutant leader in front of the gang, which splinters. Hearing of his rival's return, the Joker wakes up, kills a whole studio audience on a TV show and ends up dead at a fair, breaking his own neck. The government sends Superman to stop Batman. With Oliver Queen's help and a kryptonite arrow, Batman wins, but suffers a heart attack. After the funeral, Carrie digs him up: Bruce faked his death and leaves with his followers to keep up the war.
