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.

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.
