Wartime spy thriller. Richard Greene stars as war correspondent Bob Randall, who returns from Dunkirk to report on Nazi atrocities committed during the Blitzkrieg, and to deliver a stark warning about the traitors who aided the Germans in their conquest of Europe. He is outraged to discover that the 'People for Peace Society' in England are campaigning to appease the Germans, and tries to expose them for the fools they are - only to have his newspaper stories censored by Home Security. As the Blitz rages in London, Randall and fellow journalist Carol Bennett (Valerie Hobson) uncover an even more sinister side to the Society. Do they have advance knowledge of German bombing raids? And who is really controlling them?

World War Two drama starring James Mason.

But once they penetrate the Nazi headquarters, can they survive long enough to get their information to the British troops? Roland Culver, Michael Wilding and Hugh Williams co-star.
