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. In Canada and Scandinavia, the expansion of the gang has led to violent turf wars involving shootings, bombings and hundreds of deaths.

In 1984, with Ethiopia in the grip of famine, Michael Buerk filed two shocking reports highlighting the plight of the sick and the dying.

Buerk returns to Africa to meet those whose lives were irrevocably affected by the tragedy first time around - including an aid worker who found herself in the impossible situation of deciding who should live and who should die - and asks whether the developed world has helped to create a nation wholly dependent on charity.
