Screen One S02E03 - The Police

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.
