Travelling to Madrid and Barcelona and through Galicia and Extremadura, Miles talks to Franco's interpreter, ministers, family friends and colleagues, those who fought against him in the war and those that stood beside him at state occasions and rallies. Alongside their stories, and those of Franco's British biographer, Professor Paul Preston, are those of ordinary Spaniards - the ETA suspect whose death sentence Franco commuted, the priest forced into hiding in Republican Madrid, the women imprisoned in the post-war repression, the schoolchildren singing Falangist songs.

But what happens to the car and the industry that developed it now? There are huge problems: a great excess of capacity, increasing sensitivity in the developed world about what the automobile is doing to the environment. This series looks back at the profound effects the car has had on our lives for the past hundred years ...and then asks what happens next, and how the industry can tackle the enormous challenges it faces.

Written by Annie Caulfield and starring Simon Russell Beale and Frances Barber.
