The “Line” is comprised of petty bourgeois hotel, restaurant, and cafe owners, etc, and these people refuse to relate to unionised workers. The series conforms to Cold War sentiment as the Belgians are depicted as confronting the Nazi Germans and subtly resisting their allies – the Communists. And yet in reality, it was the Communists who carried-out most of the fighting, took most of the risks, and suffered the highest casualty rates. The Communist Party of France was funded and directed, in-part, from the USSR and the UK. I would say the series treads an ideological tightrope very successfully. The height of the rather silly anti-Soviet script writing appears in Series 2, Episode 2, entitled “Russian Roulette”. This story supposedly depicts two airmen (from the Soviet Red Airforce) shot-down over Eastern Germany during 1943.
