Episode description
How China's barefoot doctor scheme revolutionised rural healthcare; plus M*A*S*H, the ground-breaking American TV show that taught a generation about war; the assassination of the Swedish prime minister Olof Palme; the German and Russian soldiers who fought on the Eastern Front in the First World War; and the Angel of the North, a huge steel sculpture that has become an icon for the north-east of England.
