A postcard from Hamburg

"June, 1943. Kurt Müller, fugitive member of the German resistance -- the Black Orchestra -- is working for British Intelligence in London, when he receives a mysterious postcard from his girlfriend, Gudrun, posted in Germany. It is clear that she has been abducted from their home. Kurt goes AWOL to find and rescue her. Meanwhile, Erika is engaged in an SOE operation to free a captured airman from a PoW camp somewhere in France. The two stories come together in a dramatic climax in Occupied France." --
