Citizens have been disappearing late at night and it turns out they were being kidnapped by Troggies – the descendants of citizens that chose to live underground to escape the furious pace of modern life.

Judge Dredd went down on a one man rescue mission and found they were planting bombs to bring down the Mega City from below. The subterranean dwellers and their leader Slick Willy were rounded up by the Justice Department.

Dredd was heard to say “Mega City is full of people with an axe to grind.”
