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 FÃ¼hrer’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, by overthrowing the SS and imprisoning Hitler’s closest advisors. 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: however, Fromm initially refuses. With the rewritten plan needing to be signed off by Hitler (Bamber) himself, von Stauffenberg visits the FÃ¼hrer 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.
As von Stauffenberg flies back to Berlin, Olbricht refuses to mobilize the Reserve Army until he knows without a doubt that Hitler is dead. Behind Olbricht’s back, Mertz forges his signature and issues the orders anyway. With Operation Valkyrie underway, von Stauffenberg and his fellow plotters order the arrest of Nazi party leaders and SS officers and begin to take control of Berlin’s government quarter, which will allow them to command the entire Reich. Rumors reach Berlin that Hitler survived the blast, but von Stauffenberg dismisses them as SS propaganda. Meanwhile, Fromm learns from Field Marshal Keitel that Hitler is still alive. The General refuses to join the plotters, resulting in his arrest. When Hitler reaches the Reserve Army by telephone, the SS officers are released and the plotters in turn are besieged inside the Bendlerblock. The headquarters staff flees, but the ringleaders are arrested. Most are eventually tried and executed, while some commit suicide. Von Stauffenberg shouts “Long live sacred Germany!” before being executed by a firing squad.
