Growing up in in a small town in the English midlands, Kayleigh Goodman has been repeatedly bullied in school. Even when she moves to a new secondary school to escape bullying, a new gang of bullies, Natasha Harrison and her 'crew' begin to make Kayleigh's life a misery.

Whilst being chased by this gang of bullies she stumbles into a boxing gym. Terrified at first, reluctantly, she stays in the gym and enjoys the training session. She takes to the sport like a duck to water and she learns how to fight back. Supported and encouraged by a group of wise and knowledgeable coaches she makes rapid progress and as she learns to box, she develops new friendships, and she battles bullies inside and outside the sport.

Eventually Kayleigh takes part in real boxing matches. Initially locally, then in Liverpool and in London. She even takes on a girl that had bullied her in her previous school. But can Kayleigh win a gold medal at the prestigious Harrington Box cup?
