Two members of the Secret Six, Bane and Catman, have been defined by their relationship to one man... Batman. Now that Batman has either died or vanished, allowing crime to run rampant in Gotham, they've both come to the city. But unlike a typical day, they've come to Gotham to foil a kidnapping plot in respect of Batman's legacy. And Ragdoll is tagging along as the Boy/Girl Wonder.
