He was a shining light in the German resistance movement and the bomb he placed at Hitler's headquarters could have put an end to war and genocide. Yet like most German army officers, Claus Schenk, Count von Stauffenberg, was at first a fascinated observer of Hitler's rise and his early military successes. He, too, was carried away by the triumph of the French campaign. It was a long road for this loyal follower of his commander-in-chief to become the man who tried to kill the Fuhrer on 20 July 1944. So what turned an ambitious officer from an old aristocratic family into the mastermind of a coup d'etat? What did he know about the crimes committed under the Nazi regime? Based on the latest research about the German Resistance, this documentary seeks to answer these questions.
