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

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.
