In Nazi Germany during World War II, as the tide turned in favor
of The Allies, a cadre of senior German officers and politicians
desperately plot to topple the Nazi regime before the nation is
crushed in a near-inevitable defeat. To this end, Colonel Claus von
Stauffenberg, an Army officer convinced he must save Germany from
Hitler, is recruited to mastermind a real plan. To do so, he
arranges for the internal emergency measure, Operation: Valkyrie,
to be changed to enable his fellows to seize control of Berlin
after the assassination of the Fuhrer. However, even as the plan is
put into action, a combination of bad luck and human failings
conspire on their own to create a tragedy that would prolong the
greater one gripping Europe.
