Chantelle has everything going against her. She's a good student who only wants to pass her exams and find a way out of the sink estate in Manchester where she grew up. But now her feckless mother has taken off for Spain with her latest boyfriend and she's single-handedly raising her tearaway nine-year-old brother Leon. She thinks her worst problem is the debt collectors at the door. But Leon has made some new friends: teenage gang members who have given him a mobile phone, a knife - and some drugs to hide in her flat. A part-time job seems to be the answer to Chantelle's prayers. But the violence is about to come home to her - with a vengeance. And the only person who's offering any help seems to be just as bad as the people she's trying to escape from . . .
