The film tells of a couple romantically involved despite family feuds.
Jimmy Haskell (James Stewart) is the former owner of a defunct music store. His uncle, C.J. Haskell (Charles Winninger), dislikes music and has long wanted Jimmy to join him in his health food business. Jimmy only agrees after his music store is closed. When Jimmy arrives at his uncle’s place, he is confronted by members of the McCorkle family, who play in Heidt’s band and often practice outside C.J.’s business. As C.J. hates music, he is infuriated and attempts to stop the band using the police. Unsuccessful, he is thrown a tomato by Jimmy, unintentionally. Jimmy is then made a hero by the band and the McCorkles, who do not know his true identity. Molly McCorkle (Paulette Goddard) falls in love with him.
When Jimmy substitutes for C.J. on the Haskell radio program, two band members find out his identity. They work together to devise a scheme to persuade C.J. to take a vacation. In the meantime, Jimmy takes over the operation of the business and invites Heidt’s band to play on the radio. Molly learns Jimmy’s identity, and in anger, she says the Haskell program will give away $1000 every week. Jimmy has no choice but to find a way to hand out the cash, and a federal investigator reminds him that using lottery to give the 1000 dollars is illegal.
Jimmy plans to use phone books and a roulette-style game to find winners. The Haskell program grows immensely popular and attracts lucrative advertising contracts. This reconciles the Haskell and McCorkles, paving the way for the marriage between Jimmy and Molly.
