Both Arkham Asylum and Blackgate Prison have been rebuilt and reopened, and only the Industrial District of Gotham is what remains of Arkham City. Nearly a year after the events surrounding Arkham City, a Wayne Enterprises-sponsored press conference is being held on the grounds of Wayne Manor, where newly elected Mayor Kate Spencer, Commissioner Gordon, and District Attorney Paul Coleman are talking about the progress of 'The Iron Eagle Initiative', which is the name given to the project surrounding Arkham City's closure. But, even in the midst of all the chaos.is everything really as it seems, or is there something more sinister at work going on? Cut off from civilization and facing a city running rampant with seemingly every enemy he has ever faced, Batman faces his most difficult situation yet - a situation that, maybe even the World's Greatest Detective can't even get out of. Government seals the city off from the rest of the United States, declaring it a 'No Man's Land'.

Enlisting the aid of numerous other super-criminals and villains, Gotham City plunges into anarchy, so bad that the U.S. Fueled by a thirst for vengeance, the Clown Prince of Crime is planning his most destructive sceme yet - a crime wave on, not just Gotham City, but the entire country.

That all stops compleatly when a failed attempt on Gotham's newly elected mayor leads Batman to be kidnapped and taken to Sionis Steel Mill (the last remnants of Arkham City), where an old enemy has, quite literally, returned from the dead - the Joker. Nearly a year after Arkham City has been closed down, Gotham City has settled down into a rare, relative harmony.
