College senior Rudy Bronson forms a band with other students and decides to take them to the Long Island home of Ted Grant, his mail order saxophone teacher. Grant and his manager, however, annoyed at Rudy's persistent attempts for admittance, flee to the city. The band makes one last attempt to enter the house by breaking down the door, but they are witnessed by the neighbor, Mrs. Whitehall and her charming niece Jean, who call the police thinking they are burglars. Sport, one of the band members, tells the policeman that Rudy is the famous Ted Grant and lost his key, and Rudy goes along with the deception to avoid jail. Rudy then accepts Mrs. Whitehall's invitation to perform at her upcoming benefit for orphans, because he has fallen in love with Jean. But what will happen, he worries, when Jean finds out the truth.
