From the back of the book:
"I am the Law and you better believe it!"
Welcome to Mega-City One, a city of over four hundred million people and everyone of them a potential criminal. Stretching the length of the 22nd century American eastern seaboard, Mega-City One is the most dangerous city on earth, for it is calculated that one serious crime takes place every second of every day. So dangerous, it demands a special breed of law enforcer. Here, there are no police, no trials and no juries - only the judges. It takes fifteen years to train a judge for life on the streets of Mega-City One. Fifteen years of iron discipline, rigid self-control and concentrated aggression. Toughest of all judges is Joe Dredd, a man vested with the power of instant sentence, a man whose court is the streets and whose word is the Law!
