During World War II, Wehrmacht Colonel Claus von Stauffenberg is severely wounded during an RAF air raid in Tunisia, losing his right hand, the ring and little finger on his left hand, and his left eye, and is evacuated home to Nazi Germany. Meanwhile, Major General Henning von Tresckow attempts to assassinate Adolf Hitler by smuggling a bomb aboard the Führer's personal airplane. The bomb fails to detonate, and Tresckow flies to Berlin in order to safely retrieve it. After learning that the Gestapo has arrested Major General Hans Oster, he orders General Olbricht to find a replacement. After recruiting Stauffenberg into the German Resistance, Olbricht presents Stauffenberg at a meeting of the secret committee which has coordinated previous attempts on Hitler's life. The members include General Ludwig Beck, Dr. Carl Goerdeler, and Erwin von Witzleben. Stauffenberg is stunned to learn that no plans exist on the subject of what is to be done after Hitler's assassination.
