Most timelines put the start of the Second World War in 1939, but this film argues the war's real opening moves happened two years earlier, across three continents at once. Mussolini's invasion of Ethiopia proves that the League of Nations cannot stop aggression, Hitler tests the same weakness by occupying the Rhineland and then annexing Austria, and Spain collapses into a civil war that becomes a proving ground for German and Italian weapons. In China, Chiang Kai-shek's Nationalists and Mao's Communists set aside their own civil war to face Japan's invasion, a decision that reshapes East Asia's alignment for the coming decade. The film moves between these fronts to show how separate conflicts in Africa, Europe, and Asia were already testing the international order years before Poland was invaded. Archival footage and expert narration trace how each crisis fed the next, building the case that 1937, not 1939, is when the war actually began.
