June 1940: Hitler launches tanks and troops across France, Belgium, and Holland. Germany is impoverished, has few raw materials, and no oil or currency. How did the Nazis manage to set off the cataclysm of WWII with such little money and a weak economy? Based on the work of a new generation of French, British and German historians, we take an economic, industrial and financial approach to the Third Reich, exploring the inner workings of the Nazi system through key characters who have been overshadowed by history.
