Introduction:

During World War II, Wehrmacht Colonel Claus von Stauffenberg (Cruise) is severely wounded in Tunisia, and is evacuated home to Nazi Germany. Meanwhile, Major General Henning von Tresckow (Branagh) attempts to assassinate Adolf Hitler by smuggling a bomb aboard the Führer’s private airplane. The bomb, however, fails to detonate and Tresckow safely retrieves it to conceal his intentions. After learning that the Gestapo has arrested Major Hans Oster, he orders General Olbricht (Nighy) to find a replacement. After recruiting von Stauffenberg into the German Resistance, Olbricht delivers von Stauffenberg to a meeting of the secret committee which has coordinated previous attempts on Hitler’s life. The members include General Ludwig Beck (Stamp), Dr. Carl Goerdeler (McNally), and Erwin von Witzleben (Schofield). The Colonel is stunned to learn that no plans exist for after Hitler’s assassination.

After a bombing raid on Berlin, he lights upon using the plan Operation Valkyrie, which involves the deployment of the Reserve Army to maintain order in the event of a national emergency. The plotters carefully redraft the plan so that they can dismantle the Nazi regime after assassinating Hitler. Realizing that only General Fromm (Wilkinson), the head of the Reserve Army, can initiate Valkyrie, they offer him a position as head of the Wehrmacht in a Post-Nazi Germany and recruit him into the fold. With the rewritten plan needing to be signed off by Hitler (Bamber), von Stauffenberg visits the Führer at his Berghof estate in Bavaria. In the presence of his inner circle, Hitler praises von Stauffenberg’s heroism in North Africa and signs off on the plan without fully examining the modifications.
