Claim: Valkyrie is set in Nazi Germany.

Operation Valkyrie -LRB- Unternehmen Walküre -RRB- was a German World War II emergency continuity of government operations plan issued to the Territorial Reserve Army of Germany to execute and implement in case of a general breakdown in civil order of the nation . Failure of the government to maintain control of civil affairs might have been caused by the Allied bombing of German cities , or uprising of the millions of foreign forced laborers working in German factories .   German Army -LRB- Heer -RRB- officers General Friedrich Olbricht , Major General Henning von Tresckow , and Colonel Claus von Stauffenberg modified the plan with the intention of using it to take control of German cities , disarm the SS , and arrest the Nazi leadership once Hitler had been assassinated in the 20 July plot . Hitler 's death -LRB- as opposed to his arrest -RRB- was required to free German soldiers from their oath of loyalty to him -LRB- Reichswehreid -RRB- . After lengthy preparation , the plot was activated in 1944 , but failed .
