Greg Dyke takes a bus tour through the Welsh Valleys and the life of Labour politician Aneurin Bevan, pronouncing him 'one of the outstanding men of the 20th Century'. In 1945, Bevan simultaneously launched the National Health Service and set about rebuilding a bomb-damaged Britain, in one of the most remarkable double acts a politician has ever been asked to achieve. Dyke visits the coalmines where Bevan began to hew coal at the age of 13 and explores the Tredegar Medical Aid Society, which was the blueprint for the NHS. He also reveals the close friendship between Bevan and the black American civil rights campaigner and world-renowned opera singer Paul Robeson.
