Edgar is a nice, normal, clever 11-year-old - and he's had enough of being bullied. He organises the other children into a police force, and they set out to bring justice to the school. Their law-and-order game is such a success there are no more 'criminals'. But the story takes a sinister turn when an unpopular teacher publicly humiliates Edgar and he decides revenge is rightfully his.

When Danny , the adolescent son of Kevin and Anne Harris , first shows signs of disturbance, no one seems too concerned. But the situation gets dramatically out of control.
