Three years after WWII, Europe struggles with rationing, widespread unemployment and a growing Soviet threat. Hitler's former capital lies ruined under the joint occupation and control of wartime allies bitterly at odds. With the currency worthless, the population lives on hand-outs or turns to crime and prostitution. Deep inside the Soviet Zone, Berlin appears to be an ideal target for a communist take-over, putting the defenders of democracy on a collision course with Stalin's merciless aggression. A Battle of Britain ace, a female air traffic controller, a concentration camp survivor and an ex-ATA woman pilot are just some of those trying to find their place in the post-war world. An air ambulance service offers a shimmer of hope, but when a Soviet fighter brings down a British passenger liner, Berlin becomes a flashpoint. The world stands poised on the brink of World War Three.
