The Black Flame and Catwoman do not actually appear in this story. They are disguises worn by Mxyzptlk and Bat-Mite.

Synopsis:
While on patrol near Gotham City, Supergirl is attacked by a spectral hand. Batgirl comes to her aid. Working as a team the girls are able to escape the hand which then disappears. The girls then begin a campaign to humiliate and discredit Superman and Batman.

In a series of incidents Supergirl temporarily robs Superman of his powers and upstages him. Meanwhile Batgirl makes Batman act like a coward while fighting crooks. The girls then lock Batman out of the Batcave and steal his equipment. Supergirl also takes the Fortress of Solitude and hides it from Superman. Next the girls kidnap Robin and leave both heroes powerless without even their secret identities.

When the girls the confront Superman and Batman, their real identities are exposed. Superman discovers that Supergirl is really the Kandorian woman Black Flame, while Batman discovers that Selina Kyle the Catwoman has been masquerading as Batgirl. The heroes forces the villainesses to reveal where the real Supergirl and Batgirl are being held. However, before a rescue can be enacted Supergirl and Batgirl arrive from another dimension.

Supergirl then unmasks Black Flame and Catwoman as Mxyzptlk and Bat-Mite. The two imps were once again staging a game with the heroes as their pawns. Bat-Mite tricks Mxyzptlk into returning to his home dimension before leaving voluntarily. Once they are gone, the effects of their magic tricks on Superman and Batman are reversed.
