Posing as unemployed musicians, Roy Acuff and his Smoky Mountain Boys, are being helped by Ted Gibson owner of the Harmony Inn in San Antonio, Texas. Gibson is impoverished because he keeps buying his kleptomaniac Uncle Zeke out of trouble, supports his Ma, and Grandpa. He wants to marry Jean Wallace, and doesn't know that Acuff and his musicians are traveling incognito for the radio show "Who Am I Helping?" If he guesses their identity, he wins $100,000.
