"Iconic Batman artist Jock delivers a bare-knuckle brawl through the blacked-out streets of Gotham! All they had to do was get him across town. It was the sort of mission Batman had run a thousand times. From high above the sweltering summer streets of Gotham, Batman would escort the GCPD as the dangerous metahuman super-villain known as E.M.P. was transferred from a temporary holding cell to his permanent home at Blackgate Prison in Gotham Harbor. E.M.P.'s electrical powers posed a dangerous threat, but the situation was well in hand. Until it wasn't. Now every light in Gotham is out, the police have been knocked into disarray, and a broken, bleeding Batman must fight his way to Blackgate, block by block, dragging E.M.P. behind him. But it's not just the gangs who want to make life difficult for him. The dark corners of Gotham contain many surprises...and E.M.P. has many more shocks to deliver before the night is through!"
