Hilda has forgotten to tell Zelda that their magic is due for a twenty-five-year tune-up, so they must both surrender their powers for a few days, leaving Sabrina "the most powerful woman in the house" temporarily. But her delight in her new status doesn't last after Valerie persuades her to sneak into a new nightclub to hear 'N Sync perform.
