It gets into your bones. You don't even realise it, until you're driving through it, watching all the things you've always known and leaving them behind. Young Londoners Becky, Harry and Leon are leaving town in a fourth-hand Ford Cortina with a suitcase full of money. They are running from jealous boyfriends, dead-end jobs, violent maniacs and disgruntled drug dealers, in the hope of escaping the restless tedium of life in south-east London - the place they have always called home. As the story moves back in time, to before they had to leave, we see them torn between confidence and self-loathing, between loneliness and desire, between desperate ambition and the terrifying prospect of getting nothing done.
