In their twenties and living on a rough council estate with their mum, twin sisters Lizzie and Penny Berry are complete opposites. The one trait they do share is the desire to DO something with their lives; and, as far as they are concerned, the place to get noticed is London. So when their Gran has to stay in hospital, they go to look after her flat in Chelsea... But they discover that it's not as easy to become 'It' girls as they had imagined, and West End boys aren't all like Hugh Grant.
