Any movie that starts Jewish entertainer George Jessel as an Italian accordionist named Luigi can't be all bad. In love with the beautiful Margharita (Lila Lee), Luigi lands a job in the music store owned by the girl's uncle. Ultimately, however, our hero does the Pagliacci act when Margharita evinces a preference for handsome Pasquale (David Rollins). The film's best scene takes place in a nursery full of talented tots, a sequence that undoubtedly reminded Jessel of his days with Gus Edwards' "Schoolroom" act. Exercising his droit du seigneur, Georgie Jessel sings the title tune.
