Two composers vie for their lady manager's heart as they head for Broadway.

Danny O'Neill, the leader of his college orchestra, and his roommate, trumpeteer Hank Taylor, are the oldest students on campus. One day, they meet bill collector Ellen Miller, who serves them with a summons for an overdue bill. After getting Ellen fired from her job, the pair offer her a position as their agent, and she becomes such a success that she begins to sell the band against Artie Shaw and other name bands. In self-defense, Shaw hires Ellen away from the boys and she moves to New York. There Ellen convinces Shaw to audition Danny and Hank for spots in his band, but they fail to get the job when they all but ruin the band's performance because of their childish rivalry for Ellen's affections. Forced to become musical outcasts, Hank takes a job as a bugler at a race track while Danny dresses up as a Russian dancer to get a job. Salvation comes to them in the form of J. Lester Chisolm, an elderly businessman with the soul of a musician, who becomes Ellen's benefactor. The boys finagle Chisolm into sponsoring them for a spot in Shaw's concert. When Chisolm drugs Hank at the last minute, he sleeps through the concert, but Danny achieves success at last.
