Roger Wadsworth is a salesman for a company that supplies jukeboxes with classical music recordings, as Mrs. Horton, chief stockholder of the company hates swing music. Because of that, and the fact that Mrs. Horton is the mother of his fiancée, Genevieve Horton, Roger can only sit by and watch the competitors, who sell swing-and-jive music records get most of the business. Some of the other salesmen play a joke on Roger by getting Charlie Barnet and his orchestra to make a recording which they slip into Roger's packet marked as classical. They also get showgirl Jinx Corey to tell the newspapers that she and Roger are married. Malcolm Hammond goes to Genevieve to plead Roger's case, and tricks her into making a recording as "Jukebox Jenny." This leads to further complications.
