Batman: One Dark Knight #[nn]

In "One Dark Knight Part One: Summer in the City," Batman stands vigil as a high-risk prisoner is moved from Arkham Asylum to Blackgate, the city’s most secure prison. When the convoy is ambushed and the prisoner vanishes into Gotham’s streets, Batman must track him down before his dangerous abilities spiral out of control—or fall into the wrong hands.

In the shadowed chaos of a Gotham plunged into darkness, Batman races to deliver E.M.P. to Blackgate, pursued by ruthless gangs eager to claim the prize. As the city fractures, Vasquez follows a dangerous lead—E.M.P.'s son, whose mysterious connection to his father’s power may be the key to survival.

In the shadowed depths of Gotham’s sewers, Batman faces off against Killer Croc in a desperate bid to reclaim the dangerous E.M.P. Meanwhile, above ground, Vasquez guides Brody toward a fateful confrontation, hoping to use Brody’s powers to turn them against E.M.P.—and settle a debt of vengeance tied to her family’s tragic past.
