Under pressure from his wife, Mayor Linseed replaces Commissioner Gordon with women's-rights advocate Nora Clavicle. She promptly fires all Gotham's lawmen (including Batman) and creates an all-female police department, which turns out to be the perfect way to pull off a string of bank robberies.

Shame escapes from prison, thanks to Calamity Jan, Frontier Fanny, and a 300-horsepower Sherman tank. The Terrific Trio deciphers a coded note and figures out that the robbers are planning on hitting the Gotham Opera House during "Girl of the Golden West" that night.
