Synopsis by Hal Erickson
Without his parents' knowledge or permission, Beaver (Jerry Mathers) orders an accordion by mail for a ten-day free tryout. The trouble begins when the accordion arrives -- on the 11th day. Now, Beav must not only hide the accordion, but also prevent his parents from finding out that he owes money on it. And just when it seems that things can't get any worse, the accordion is accidentally -- and irreparably -- damaged!
