J. P. Courtney wants to update the music on the radio program he sponsors, but his wife, Agatha Courtney, is the final authority and addicted to the classics and won't allow him to replace Professor Bistell and his symphonic orchestra. Conspiring with his daughter Sue and her friends, Marvo the Great, the Andrews Sisters, Anne Payne and bandleader Woody Herman, they devise a sabotage plot that gets rid of Professor Bistell, and a new sound is soon heard on the program.
