Plot

The story begins in the then-distant year of 2019. An aging Bruce Wayne, despite being in his 50s, continues to fight crime as Batman in a new high-tech Batsuit, although he has increased difficulty in handling criminals he could once subdue with finesse and they are no longer afraid of him as he has lost his mystique. In what was supposed to be a routine mission, the rescue of a kidnapped heiress, Batman suffers a mild heart attack and at risk of being beaten to death by one of the kidnappers, is forced to use a gun to fend him off. Despite not killing the man, Bruce is ashamed and, knowing his frailty and fearing that he will eventually succumb to his murderous temptation if he continues his crime-fighting, decides to retire from being Batman for good. By this point in his life, his butler Alfred Pennyworth has died and his close allies have all either retired or died of natural causes. His crime-fighting partners are still alive, but estranged from him following their retirements from their alter-egos and possible falling outs with him. His rogues' gallery are all either in prison, institutionalized, reformed or deceased. He has also severed his ties with other superheroes.
