James Stewart sings with Horace Heidt and his Orchestra on his uncle Charles Winninger's radio show, while falling for Mary Gordon's lovely daughter Paulette Goddard. That's all there is to the plot, really, and Stewart later publicly declared this the worst of his films. Viewed today, it has a quaint period charm, though songs like With a Knife, a Fork and a Spoon don't exactly light any fires. The title was also the name of a popular long-running radio show featuring bandleader Heidt, and this film was really made to capitalise on his appeal.

Jimmy, the owner of a failed music shop, goes to work with his uncle, the owner of a food factory. Before he gets there, he befriends an Irish family who happens to be his uncle's worst enemy because of their love for music and in-house band who constantly practices. Soon, Jimmy finds himself trying to help the band by getting them gigs and trying to reconcile the family with his uncle.
