Quiet American in Prague (1978)

In the era of normalization, even seemingly buried agent stories came back. This one takes place in the immediate post-war years and tells the story of the discovery of a spy network that an American diplomat was spinning on Czech territory. He was unsuccessful: first, a close associate, who was proven to have collaborated with the Nazis during the war, committed suicide, followed by the intervention of the vigilant Security Service. However, the fleeing Americans were joined "in return" by a Czechoslovak agent... This naive adventure story could hardly be taken seriously. The book, which served as the basis for the film, was written based on actual events that took place in 1948.
