Winston Churchill spent the first weeks in the prime minister's chair in the first months of World War II. Thanks to the script of Anthony McCarten and the great Gary Olmaman, we have a chance to see a man, not an icon. We meet him as a witty and brilliant statesman, a vigorous member of the Parliament, a 65-year-old candidate for prime minister in a time when Europe is falling, burning in the conflagration of war. The allied countries are still losing the battle against the Nazi forces. The British army is on its own in France. 300,000 British soldiers are stationed on the beaches of Dunkirk. Under these circumstances, Chamberlain's government resigns. Winston Churchill becomes the new prime minister of Great Britain. He has against himself members of his party and the king - George VI (Emma laureate Ben Mendelsohn), who is skeptical about Churchill's actions. It is May 10, 1940. Before Winston Churchill, perhaps the most difficult decision in life - to negotiate with the Nazis a peace pact that would save the British nation from the nightmare of a war, or incur unforeseen costs and face the enemy?

His wife, Clemmie (nominated for Oscar® by Kristin Scott Thomas) supports him in making his decision. Inspired by the attitude of the British, he decides to focus on their ideals - freedom and love for peace. He knows that he must warm up society to fight, prepare a speech that will move the nation. Support is tireless secretary (Lily James). And so, they face the greatest test, Winston Churchill forever changing the course of history.
