Talent scout Rush Blake has gone through his advance from Consolidated Broadcasting Co. without finding a single new act. After he is fired, he goes to a restaurant looking for friends who might loan him train fare out of town, and discovers singing waiter Buddy Clayton, who draws a large female audience. Sure that he will be equally successful on the radio, Rush convinces Buddy to sell his car and come to New York with him. There Rush wangles an audition for Buddy, but he sings the same barroom song that was so popular at the restaurant and fails the audition. Afterward, Peggy Cornell, the "Cinderella Girl," visits Buddy at his hotel. Buddy sings her a song that children's radio performer Pete has just written, and to everyone's surprise, his voice is beautiful. When Sharpe, the head of the station, refuses to give Buddy another audition, Peggy pretends to faint on her own show, "The Carlotta Soap Program," and Buddy takes her place. Mrs. Brokman, the wife of the sponsor, loves his voice, as does everyone who hears it. Soon Buddy is the new star of "The Carlotta Soap Program," and Peggy, whose contract was bought out, is on her way to being a Broadway star. When news of Buddy's engagement to Peggy makes the papers, Sharpe is afraid that women will lose interest in Buddy if they know he is married. By lying to both Buddy and Peggy, Rush manages to break up the engagement, but Brokman now thinks that Buddy is involved with a married woman, thus compromising the purity of his soap. Contrite, Rush finds him a job on Long Island, luring Peggy, Sharpe and the Brokmans to hear him. When Peggy and Buddy sing a duet, it is clear that no one minds if they get married after all.
