When Sabrina is disappointed that her aunts won't let her stay out late to see the famous rock band Violent Femmes, Hilda and Zelda decide to transform themselves into teenage chaperones as a compromise. But they're the ones causing the trouble when "Hillary" clashes with a security guard and a high-school boy falls for "Zellery." After proving that even teenage aunts can be embarrassing, they apologize by giving Sabrina her very first flying lesson - aboard a vacuum cleaner.

As Sabrina and Harvey grow closer, her aunts reveal that when a witch kisses a mortal for the first time, the mortal turns into a frog. Unable to stop herself, however, Sabrina kisses Harvey, and must find a way to change him back.
