August 1939. Shimmering heat in Central Europe. The grain is mowed. Holiday season. It might be carefree days, but there's something disturbing in the air. Some say a new war is imminent. The others swear the peace is safe. In this restless August, the world is watching the Obersalzberg. Adolf Hitler spends his summer here. From here he dares a risky game. Hauke Friederichs tells the story of that summer when the world was plunged into chaos on September 1, 1939 at 4:45 a.m. A world conflagration arose from the flying sparks, and nothing was the same as before.
