Batgirl pays a visit to Commissioner Gordon to express her concern over his new “Get Tough On Costumed Villains” policy. She suspects that he is experiencing some kind of post-traumatic shock because of the three days he and the men spent lost in suspended animation. Unable to persuade the Commissioner of the danger Harley, Ivy and Catwoman are in, Batgirl takes the unprecedented move of breaking them out of prison. They are safe, but Batgirl has been declared “Public Enemy Number One.”

Detective Montoya is arguing with Commissioner Gordon when the call comes in that Batgirl has been spotted on the North Side. As they head off, Batgirl is sighted on the West Side. Then the South Side. Each of these “Batgirls” is unmasked, revealing them to be Harley, Ivy and Catwoman. Under cover of this diversion, Barbara Gordon slips into the unmanned Police Headquarters and steals the key to the Dangerous Evidence Vault from her father’s drawer. As she slips the key into the Vault she is surprised by Detective Reesdale.

Detective Reesdale assumes Barbara has the Commissioner’s permission and gives her the "grand tour" of the vault. Reesdale lets slip some information that disturbs her. Barbara secretly steals some of the evidence confiscated from Mr. Freeze and slips away. In the glare of the Bat-Signal, Barbara confronts her father. When he insists he has incontrovertible evidence implicating Batgirl, Barbara’s fears are realized. Her eyes turn to steel. She forces the Commissioner into the Batsignal and to certain death. What’s wrong with this picture?

The Commissioner, twitching in the Batsignal, explodes into a pile of gears and wheels and microchips: He’s a Robot! Who is behind this robotic Commissioner? None other than the Commissioner’s supposedly loyal assistant, Dora Smithy. Sister to Nora. Sister-in-law to Mr. Freeze. The Robotic Replacement was designed to crack down on the costumed villains – like Mr. Freeze – whom Dora blames for her sister’s fate. In a final pitched battle in an old Mr. Freeze hideout, Dora falls into a vat of cryo-solution and is turned into a female version of Mr. Freeze. The very thing she hated.
