Young Piccolo Grande lives in his fine old family home. But one fateful afternoon his neat and ordered life is turned upside down and inside out when noisy, round and red-faced Annabelle bursts into his life. She claims to be his great aunt but Piccolo recognises her for the angel she is - a guardian angel, sent to mind Piccolo. But where Annabelle goes, disaster follows, and in two shakes of a feather it is the boy who is minding the angel.
