Welcome to Mega-City One, a city of over four hundred million people and every one of them a potential criminal. Stretching the length of the 22nd Century North American eastern seaboard, Mega-City One is the most dangerous city on Earth – a serious crime takes place every second of every day. This is a city so dangerous that it demands a special breed of law enforcer. Here, there are no police, no trials and no juries – there are only the judges.
