Katie wordt gepest op school. Een dakloos meisje komt haar te hulp, wanneer Katie zich probeert te verstoppen voor haar kwelgeesten op een vuilnisbelt.

Katie is being bullied at school - and cannot get anyone to believe her. She feels frightened and alone . . . until one day when she is cornered by Ivy and her fellow bullies on the town dump. Katie is terrified, there is nowhere left to run. But suddenly, as if by magic, a girl called Zan rises from the rubbish in the dump and leaps to Katie's defence. But Zan is not willing to talk to Katie - all she wishes to do is keep her identity a secret. Slowly Katie learns the truth about Zan, and when she does, she realises Zan has much more to lose than the safety of her cardboard box.
