Radio singer Joan Abbott, known as the "Crunchy-Wunchy Thrush", does not want to renew her contract with the cereal sponsor, as she wants to go to college. But her guardian, her Uncle Willie signs the contract in order to pay off his own debts. But this time Joan won't take no for an answer and enrolls under an assumed name. When Joan goes missing, the radio institutes a search for Joan via a publicity stunt.
