On board a riverboat bound for Creek City, singer Jimmie Davis, who is going to become half-owner of a land development company willed to him by his uncle, shares a cabin with traveling salesman Dixie Dalrymple. After Dixie invites Jimmie to perform in a concert he is putting on for the other passengers, Jimmie is persuaded to participate in a crooked card game run by Judge Homer Kenworthy and his associates. However, with Dixie's intervention, Jimmie wins handsomely, then accuses the gamblers of trying to cheat him.
