They may be twin sisters, but Lizzie and Penny Berry are complete opposites - Penny is blonde, thin and outrageous; Lizzie quiet, thoughtful and definitely not thin. The one trait they do share is a desire to DO something with their lives, and as far as they are concerned, the place to get noticed is London. Out of the blue they discover they have a grandmother living in Chelsea - and when she has to go into hospital, they find themselves flat-sitting on the King's Road. But, as they discover, it's not as easy to become It Girls as they'd imagined, and west end boys aren't at all like Hugh Grant.
