“Clash of Futures” explores the dramatic era of the 1920s and '30s. The eight-part series follows the fates of extraordinary men, women and children from France, Germany, Italy, Great Britain, Austria, Sweden, Poland and the Soviet Union using their own diary entries, letters and memoirs. These are people drawn into the war by their convictions, who with their loves and decisions bring the history of Europe with all its contradictions to life.
