Tom, Mia and Oliver are the victims of a gang of bullies - who waylay them on the way home from school. It&apos;s not at school, so the teachers wouldn&apos;t be able to help, and they don&apos;t want to tell their parents, so there&apos;s only one option - to pay up. At first. But as the pressure builds more and more, a terrible suspicion begins to surface: could one of the three friends be helping the bullies? And if so, just who is... the traitor?
