One unauthorized phone call at 11 PM on July 30th, 1914 started World War One. The man who made it had no permission to do it — and 20 million people paid the price.
Most people know about the assassination of Archduke Franz Ferdinand. Almost nobody knows about the phone call 32 days later that actually detonated the war. In this documentary, we reveal the exact moment German Chief of Staff Helmuth von Moltke called Vienna without authorization, committed Germany to total war, and locked every empire in Europe into a collision no one could stop. We trace the domino chain — from a driver's wrong turn in Sarajevo, to the Kaiser's blank check, to Moltke's call, to the moment the German army became a machine nobody could switch off. This is the story of how World War 1 started, the real history behind the July Crisis of 1914, and the butterfly effect that shaped the entire 20th century.
