The assassination attempt on Hitler on July 20, 1944, succeeds. What happens on July 21? On July 20, 1944, the conspirators led by Count Stauffenberg blow up the Führer. However, the jubilation over Hitler's death is quickly followed by disillusionment: the assassins lack sufficient support from the population and the Wehrmacht. Their desperate situation forces them into an alliance with Heinrich Himmler and the SS. At the last moment, Germany averts defeat in the world war through a nuclear strike. The Germans compel the Allies to a peace that guarantees the Reich the borders from April 1940. Germany becomes the third superpower alongside the USA and the Soviet Union. A few years later, CIA agents appear at Knut Werdin's door. The former SS officer had betrayed Germany's nuclear rearmament to the Americans and has since been living under a false name in the USA. Now he is to be brought back.
