The epic continues, and blood will spill. Catwoman and the Riddler have pulled off the perfect crime and are now in possession of the most valuable object in the DCU. But how long can they hold on to it with not only Batman on their tail, but also a terrifying new villain known simply as the Help?

A shocking heist has the mysterious and deadly figure called the Help cutting his way through Gotham City in search of Catwoman and the Riddler and their stolen artifact. Only the Dark Knight stands between this strange new villain and his prey…but can even Batman stop his bloody rampage? Tick-tock…the clock is drawing nearer to the Killing Time!

In Batman's second year of his crusade against crime, while he is still changing and perfecting his craft and the art of the vigilante, the cowardly lot of criminals in the city are changing as well—giving rise to darker, specialized rogues. Two of the new, colorful rogues, Riddler and Catwoman, have just pulled off the heist of the century, robbing Wayne-Gotham Securities, getting away with 1.5 million in cash. After the robbery, after a few dead guards, with all of Gotham including Batman searching for them, they meet with their backer, Penguin, the man who will wash their money, take his cut, and secure their escape. And Riddler shoots Penguin in the gut, grabs the loot, and turns to Catwoman. “It’s ours, all of it. All we got to do is escape this city.” Riddler and Catwoman take to the road, both weighing how long they can go before they need to take the other out. And as they move about the city they’re hunted by an inexperienced Batman who knows two things: One, he’ll need to be better than he’s ever been to catch these two psychopaths; two, Penguin survived and if he gets to them first, it’ll be a bloodbath like Gotham’s never seen.
