Patty Nelson lands a job as a singer with orchestra leader Al Tyler, and tours with the band as "Patty Hart." Patty's father Russ is dismissed from his radio-station job, and the disc jockey selected to replace him is Al Tyler. Patty rushes home to keep Russ company on the air for the final few days, and Al wonders why she suddenly walked out on him. The new "Patty and Russ" radio show catches on, causing complications with Al and the radio-station bosses.
