Oracle asks Batgirl to give Onyx a hand. Onyx has found herself cornered by members of Killer Croc's gang, but with the arrival of Batgirl, the two women are able to turn the tables on the thugs. Meanwhile, Black Mask commandeers journalist Arturo Rodriguez and his film crew for the scoop of a lifetime, as he leads the criminal classes of Gotham City on an assault on the Batcave. Only, as Oracle soon realises, Black Mask's information is slightly wrong, and the building he thinks of as the Batcave is actually Oracle's clocktower.
