A new heroine has arrived in Gotham whose identity is a mystery— even to Batman. During patrol, the Dynamic Duo spots her trying to stop one of Penguin's shipments on Gotham's interstate, using a plasma rifle to send the Penguin's truck with its driver off the bridge. Batman and Robin saves the driver from falling to his death. Batman must figure out who Batwoman is and stop familiar enemies, the Penguin and Rupert Thorne, from selling illegal weapons to the fictional nation of Kasnia. The two employ Carlton Duquesne, a gangster, to provide protection. Batwoman's main focus is on illegal activity by the Penguin, Thorne, and Duquesne. Despite taking the symbol of the Bat as a sign of justice, Batwoman sullies the Bat prefix by taking out criminals with ruthless and dangerous techniques. She seems uninterested in sparing the lives of her adversaries. Batman, with Robin, sets out to stop the Batwoman from making mistakes as she tries to take out the villains, and as he encounters numerous twists, setbacks, and apparent false leads in determining her true identity. The newest gadget on display is a wind glider used by Batwoman that utilizes some of the most advanced technology ever seen in Gotham City. Bruce Wayne, Batman's alter ego, also becomes involved with a new lady in his life: Kathy Duquesne, the crime boss's daughter.
