Hardly, Batman recently finished bringing the most dangerous escapees from the last murderous riot to Arkham Asylum at the GCPD, to be kept there in cells while waiting for the Asylum to be rebuilt, before leaving of the city to confront the League of Assassins. However, in his absence, the dead rise, with hundreds of zombies attacking the city. The GCPD is targeted and despite the Commissar's best efforts, his men are overwhelmed... their only hope of escape is to work with the imprisoned villains. Of course, no one really trusts each other, but if they want to live a little longer, they will have to momentarily put their differences aside to face the flesh-eating dead. In the end, they will survive like this but alas it seems that it is only to quickly return to the fundamentals of their relationship...
