Patty Nelson, using the name of Parry Hart, auditions for and gets the job as a band-singer with Al Tyler's orchestra. Al, of course, falls in love with her and she with him. Back in Los Angeles, her father is a disc jockey and objects to her career choice. At a party, Al announces he is leaving the band and going to Hollywood to replace a disc jockey named Russ Nelson, who is too old and out-of-touch. Not knowing the man is Patty's father, Al does not know why she ran away. She flies to Hollywood to help her father. Al shows up, and after a couple more plot developments, all three team up on the air.
