Really great Czech film of the 60´s. I think the best picture by the director Zbynek Brynych. Armin Braun (performed by Miroslav Machacek) is a doctor of Jewish origin. In spite of the fact he could be killed by the Nazis and the whole block-of-flat with him, he is performing an operation of an injured revolter. While the operation is finished he has to find morphine to give it to the revolter because of big pains he has after the medical help.
We can see the excellent performance of Miroslav Machacek in the monologue part (by the way which lasts 3 minutes!!) in which he is deciding to help or not to help. I can recommend this movie to everyone who likes great acting in a good story.
