This series explores great cities and the criminal underworlds that lies beneath the surface.
Each programme takes one great city and looks at its history, from the underbelly up, through the story of the organised crime groups which have made it home. Part travelogue, part history series, we examine how the geography, history and culture of each city have influenced each underworld community.
