Batman is missing. A little over a week ago, The Dark Knight went silent while investigating a series of chemical based murders perpetrated by The Joker during a citywide crisis. With no Batman to arrive and stop him, The Clown Prince of Crime disappointedly turned himself into the GCPD, sparking a series of spectulatory concerns from Gotham City citizens that their hero had disappeared. Even those closest to him, such as faithful butler Alfred Pennyworth, have been unable to locate his tracker's signal ever since it went offline somewhere near The Narrows. Some of the city's vigilantes such as Nightwing, Red Robin, Robin, Huntress, Oracle and Batgirl have been patrolling the island nonstop in search.
One week later, and his signal's just become active again. But despite Alfred's attempts to contact him, Batman is unresponsive to any communications link or even the Bat-Signal, which Commissioner Gordon keeps lit in the hopes that he'll answer the call. With the assumption that he is somehow incapacited, Alfred assembles "the family" to come up with a plan of action to locate Batman and bring him back.
But is it too late? Is this The Caped Crusader's final hour, with an active beacon merely there to taunt those hopeful in his safe return? And even if he's still alive, who was responsible for his disappearance in the first place? Only one hint remains tied to the perpetrator: a recent mass breakout at Arkham Asylum has left some of it's more infamous patients on the loose, and most have yet to be recaptured. And with the rumors of Batman's demise, they're running amok.
With members of teams such as the JLA and Outsiders either unresponsive or too busy to help out, it's up to only the closest aligned to the Bat to find him and stop the chaos before Gotham burns.
