Eternal sea of death

A few years after the end of the World War II, the world becamed mired in the Cold War. Two camps faced off against each other. One, the Soviet Union and its subjugated countries. The other, the free world led by the USA. An arms race begun. The threat of another World War loomed over the world. This time a nuclear war. A true story of Ryszard Kukliński, a Polish colonel who pretty much single-handedly saved the world from total annihilation. Easily one of the best Cold War espionage thrillers. Directed by Wladyslaw Pasikowski.
