Impresario Thomas Sullivan arrives in Ossawatomie, Kansas, to debut a new musical show written by local boy Gene Harris. After auditioning with a song by her bookkeeper boyfriend Brian McBride Sullivan hires Millicent Lloyd and takes her to New York City, where she becomes a famous singer. Brian, arriving in the city with a new opera, keeps his presence secret from Millicent until he has achieved success. But Harris suffering writer’s block steals Brian's work and presents it to Sullivan as his own. With the help of music publisher Gus Hertz, Brian exposes Harris and reclaims his composition. He and Millicent are reunited, and the opera goes on to enormous success.
