Synopsis: London, 1940. The war is taking its toll. Now, France has fallen swiftly to the enemy, resulting in a disaster of immense proportions. As virtually all of Western Europe is conquered, England braces itself for an inevitable invasion by German troops. The only hope to defy Hitler is the Royal Air Force. But as German U-boats destroy the shipments of aircraft as quickly as the US factories supply them, the Allies are desperate for new fighter planes.
