1983. The world holds its breath as the two superpowers United States and Russia are arming themselves against each other with thousands of nuclear missiles. On September 26, Russian radars intercept five nuclear missiles on their way to Russia. Stanislav Petrov is commander-in-chief. The decision that would start World War III rests on his shoulders. Should Russia fire nuclear missiles at the United States in defense? Today, the world still exists, but Petrov himself is a ruined man. A man who, in his own words, is not a hero and who went against all protocol, relying on his own instinct instead of the computers. 'The Man Who Saved the World' is a true pearl. Simply heartbreaking. An epic Cold War thriller that sends shivers down your spine, while also being an extremely gripping story about a man who actually saved the world, but lost his job, his wife and his dignity. A truly wonderful and very fascinating film. I have never seen anything like this before. It combines narrative and documentary filmmaking for a true and incredible powerful film!
