Addasiad Cymraeg o un o glasuron Roald Dahl, George's Marvellous Medicine. Mae rhieni George i ffwrdd am y diwrnod, ac mae arno chwant gwneud rhywbeth am ei fam-gu. Mae 'rhywbeth' yn golygu mynd i'w thŷ, casglu pob math o gynhwysion ych-a-fi a gwneud cymysgedd hud sy'n mynd i wneud iddi ddiflannu. Ond yn lle diflannu, mae'n mynd yn fwy.
