The Case of Helvig Delbo / 1947

A true story of wartime espionage reconstructed for television by Robert Barr. In Denmark in 1943 twelve patriots who had been aiding Allied airmen to escape to Britain were rounded up by the Gestapo. British Intelligence Officers found one clue. It pointed to the traitor being a girl. With the aid of patriots from the Norwegian and Danish underground they tracked her down... and the flow of airmen escaping to Britain began again.
