It helped gather respect for the medium and set the bar for subsequent writers. Batman: The Dark Knight Returns The book is set in the 21st Century although it seems to retain many elements of the Cold War culture. It is a disturbing world where criminals have run amok in the absence of superheroes. Gotham City is terrorized by a gang of teenage murderers, the Mutants. Bruce Wayne, now 55, has been retired from crime fighting for ten years following the death of the second Robin, Jason Todd. Attempting to bury his guilt over Jason's death, Wayne has turned to alcoholism and near-suicidal recreational activities. In an effort to prove to the world (and himself) that one's personal demons can be bested, Wayne has generously funded the rehabilitation of Harvey Dent (a.k.a. Two-Face). There are two events that push Wayne back into the identity of Batman. The first instance was a chance meeting with two Mutant gang members on the very spot where his parents were killed years before, while the second was Two-Face’s immediate return to crime, despite the years of psychological and cosmetic rehabilitation. The criminals he now faces are not as organized as they had been, rather they are an unfocused band of kids who kill for money, drugs, or just for thrills. Gotham City has also changed. Whereas the public once hailed Batman as a hero standing up for the citizens of Gotham, now there are some who cry out that Batman is violating the villain’s civil rights. The media, the Mayor’s office, even police officers start to debate Batman's role in society. The one change that Batman notices the most is the change in himself. He’s older now, not able to leap as easily from roof to roof on as little sleep as he used to. His body takes longer to recover from blows and he gets winded much quicker than he ever remembered in the old days. He has had to accept that he has limitations. The episodes find Batman foiling a plot by Two Face to blow up Gotham’s twin towers, Joker appearing on a parody of the David Letterman talk show, killing everyone in the audience, and fighting Superman, who works for the President of the United States.
