Following the events of Infinite Frontier #0, The Joker is the most wanted man in the world! But the Clown Prince of Crime is several steps ahead of law enforcement—and he’s on the run overseas. James Gordon, facing retirement, realizes this is the manhunt of his life and the last piece of a storied career…but what mysterious and deadly forces are also in pursuit of The Joker? And in the backup story, following the events of the smash hit Punchline #1, DC’s most controversial new villain navigates the infrastructure of Blackgate Penitentiary—while on the outside, Harper Row takes up the mantle of Bluebird to stop her brother from falling under Punchline’s influence.

Ahem! You better read this closely, ’cause we’ve got a red-hot relaunch on our hands here—and I should know! Harley Quinn here to let everyone know that I got a brand-new monthly series here with a brand-new status quo. I’m coming back to Gotham City to make up for the sins of my past, and help the city recover from “The Joker War”! But there’s no welcoming committee waiting for me, your favorite Maid of Mischief! And between you and me, some real creeps are working to keep the city broken. We can’t let that happen, can we? Rising-star writer Stephanie Phillips, my new partner in crime, takes me into a bold new era with her partner in artistic crime Riley Rossmo, who I gotta say designed a real nice new costume for me. You’re not gonna wanna miss this one, folks!
