The strand opens with a documentary on the seemingly unstoppable rise of some of the world's most dangerous men. The Hells Angels Motorcycle Club's membership is rapidly growing in number, with new sub-factions springing up across the world, everywhere from Brazil to Liechtenstein. The rock-loving bikers have for many years been associated with violence, but many police officers now believe that the Angels have also become a sophisticated international crime organisation, with links to the wholesale trafficking of drugs.
