As a way to settle a dispute over who will claim Gotham, Joker, Penguin and Riddler have a contest to see who can capture Batman and discover his true identity. While Batman prepares to stop all three, his ally in the police force is compromised when Rojas discovers that Yin has been helping him. Soon she and Batman find themselves trying to stay ahead of the police while apprehending the three criminals, though help may be on hand in the form of Police Commissioner James Gordon, who believes that only Batman can stop Joker, Penguin and Riddler from bringing mayhem on Gotham’s streets. As a result of their heroics, Yin is reinstated to the GCPD, and Batman’s charges are dropped, as the police accept his work, even installing the Bat-Signal.
