This is loosely based on the true story of a member of the Czech underground assasinating the nazi regional governer, a ruthless fellow they call 'the Hangman'. The story revolves around the assasin and the family that unknowingly hid him from the gestapo. When questioned by the gestapo, the family says the guy was there to see their daughter, who happens to be engaged to another fine gentleman. So this little situation complicates the story, as the gestapo detective,a very ruthless chap, tries to catch them in the lie. From there the story moves along in chilling fashion when 400 townfolks are rounded up to be executed in groups of 10 each day until the assasin is turned in. This causes people to question their inner strength and makes them wonder if it is worth it to sacrifice themselves to keep him hidden. The story gets resolves in a very clever way which I will not reveal. The movie has that film noir/Hitchkockian feel to it with the protagonist being chased down and making clever escapes by the skin of his teeth. Although the movie drags a bit here and there, it ends up being a worthwhile suspenseful drama and also makes you think a bit about what would you do if you were put in that situation.
