In 1984, with Ethiopia in the grip of famine, Michael Buerk filed two shocking reports highlighting the plight of the sick and the dying. The harrowing images prompted aid efforts from around the world, yet 20 years on the situation remains desperate, with twice as many people now on the brink of starvation. 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.
