Batman works desperately to find a bomb planted by the Joker while Amanda Waller hires her newly formed Suicide Squad to break into Arkham Asylum to recover vital information stolen by the Riddler.
Amanda Waller declares to Batman, "Checkmate," which is also a subdivision of Task Force X.
Batman saves a female hostage from a criminal by shooting his grapple-gun's hook into the wall behind them, then retracting it so that a chunk of the wall whacks the criminal in the head.
