Amiable, wisecracking piano teacher Polly becomes involved with some shady music publishers. She also happens to be infatuated with her music-loving dentist Henry, who is not quite as romantically inclined as she is. Polly manages to ensnare her roommate Eileen, Eileen's fiance Jimmy, and Henry in some shenanigans involving the rights to the song "Kansas City Kitty." The comedy is mixed with several up-tempo novelty tunes from the Big-Band era.
