Bob Jordan is an aspiring songwriter with a melody stuck in his head. Naive in the ways of love, he's having some trouble writing the lyrics for his would-be hit. Barbara, a fellow musician and secret admirer, helps him finish the romantic ballad. "Cinderella" becomes an instant smash, and as Jordan's career takes off, lovelorn Barbara can only watch as her man slips away. Fame is a fickle thing, though, and Bob's flirtation with the fast life is short. Loveless and jobless, his agent has a brilliant idea to get his career back on track - a Cinderella contest. The gimmick is simple; at Jordan's next show, every available woman in the audience will bring a single slipper. The owner of the slipper that Bob selects will be invited upstage to join him in performing a duet of his signature song. The big night arrives, and Barbara happens to be in the audience. Will he finally make the right choice?
