The Catwoman "steals" the voice of a television talk-show host in the middle of an interview with Bruce Wayne. She plants clues to suggest either the Joker, Riddler or Penguin may have committed the crime. In the meantime, she has fooled Commissioner Gordon into thinking she has gone straight. She makes her first mistake when she masquerades as Miss Klutz, a dance instructor visiting Wayne Manor. Allergic to dogwood, she sneezes and gives herself away. Her next target is to "steal" the voices of British singers Chad and Jeremy. Batman and Robin eventually track her to a dance studio, where a fight erupts. After it appears the Dynamic Duo has triumphed over Catwoman's forces, she drugs them. The heroes are placed inside a chamber where the sounds of water dripping will be magnified many, many times and drive them insane.

Batman and Robin escape Catwoman's trap by hitting the precise note needed to shatter the glass chamber in which they're prisoners. They quickly get on the trail of Catwoman. The feminine feline criminal eventually "steals" the voices of Chad and Jeremy, Commissioner Gordon and talk-show host Allen Stephens. She blackmails the British government, which faces the lost of revenue from the taxes on Chad and Jeremy's performances. Batman and Robin eventually capture Catwoman and her gang, but not before Batman and Catwoman express obvious affection for each other.
