The Invisible Army is a tribute to the activities of the Danish underground during WW II. Set in Copenhagen, the film juxtaposes dramatic sequences with actual footage of sabotage activities against the Nazi troops. The most startling "actuality" clip shows a German soldier running down a street with his head on fire. Curiously, the dramatized portions suggest that certain members of the Underground weren't terribly bright, and thus brought about their own deaths. The winner of several Danish film awards, Invisible Army was released to the U.S. in a censored version; most of the violence was left intact, but a steamy boudoir scene was considerably toned down.
