The Catwoman, planning to steal the voices of visiting British rock singers Chad & Jeremy, demonstrates her new Voice-Eraser by using it on a morning talk show host. She later uses her fiendish invention on Commissioner Gordon, but not before he tells her where the British rock duo will be staying in Gotham City, which turns out to be stately Wayne Manor. In order to gain access inside the manor, The Catwoman disguises herself as Miss Klutz, a teacher from Duncan's Dance Studio, and arranges to give Dick Greyson a free dance lesson. She quickly gasses everyone asleep and beats a hasty retreat after her allergies to a nearby dogwood plant causes her to sneeze off her disguise!

Later, Batman and Robin pay a visit to The Dance Studio. There they make quick work of Catwoman's cronies, Eenie, Meanie, Miney and Moe and attempt to apprehend The Feline-ous Femme Fatale, but she subdues them both a knockout drug and transfers them to a giant echo chamber, where a dripping faucet magnified 10,000,000 times, threatens to reduce their brains to mush!
