The story recounts the beginning of Bruce Wayne's career as Batman and Jim Gordon's with the Gotham City Police Department. Bruce Wayne returns home to Gotham City at the age of twenty-five from training abroad in martial arts, manhunting, and science for the past 12 years, and James Gordon moves to Gotham with his wife, Barbara, after a transfer from Chicago. Both are swiftly acquainted with the corruption and violence of Gotham City, with Gordon witnessing his partner Detective Arnold John Flass assaulting a teen for fun.
On a surveillance mission to the seedy East End, a disguised Bruce is propositioned by teenaged prostitute Holly Robinson. He is reluctantly drawn into a brawl with her violent pimp and is attacked by several prostitutes, including dominatrix Selina Kyle. Two police officers shoot and take him in their squad car, but a dazed and bleeding Bruce breaks his handcuffs and causes a crash, dragging the police to a safe distance before fleeing. He reaches Wayne Manor barely alive and sits before his father’s bust, requesting guidance in his war on crime. A bat crashes through a window and settles on the bust, giving him the inspiration to become a bat.
