Johnny Mack Brown stars as a songwriter who gets thrown out of his room because he plays the piano at night. After his piano is smashed while moving it, his landlord (Clyde Cook)lets him use a piano in the building where he is a night watchman.
Little do they know, however, that they are in a recording studio and the microphone is on. When the music starts, the guys in the control booth shut off the boring speaker and pipe the music through, which causes an avalanche of mail wanting information about the song, "Someone." The search for the songwriter starts a competition between battling business partners (Joseph Cawthorn, Albert Conti) and the radio station owner.
Sally O'Neil gets top billing and plays the girlfriend with that Jersey accent. Henry Armetta is the hapless piano mover, Blanche Frederici plays the landlady. The terrific song, "Someone," was written by Oscar Levant.
