Frank Derrick is 81 ... and he's just been run over by a milk float. It was tough enough to fill the hours of the day when he was active, but now he's broken his arm and fractured his foot, it looks set to be a very long few weeks ahead. He watches DVDs, spends his money frivolously at the local charity shop and desperately tries to avoid the cold callers knocking on his door. Emailing his daughter in America on the library computer and visiting his friend Smelly John used to be the highlights of his week. Now he can't even do that. Then a breath of fresh air comes into his life in the form of Kelly Christmas, home help. With her little blue car and appalling parking, her cheerful resilience and ability to laugh at his jokes, Kelly changes Frank's life.
