In the months following the death of Harvey Dent, Batman, still a wanted fugitive, is pushed to his limits as a new crime wave hits Gotham. Batman's search to find who's responsible leads him to a showdown with the masochistic serial killer Victor Zsasz. Meanwhile Gotham's newest crime boss, a mysterious figure known as Scarface, has an meeting with Edward Nigma, an FBI agent, sworn to bring down Batman at all costs.
