12 February 1945, Germany. Max Otto von Stierlitz, a respected SS-Standartenführer in the Ausland-SD, is in fact Soviet spy Maxim Isaev, who has infiltrated the German establishment many years ago. Though Adolf Hitler is determined to continue the Second World War, Walter Schellenberg convinces Heinrich Himmler to conduct secret negotiations with the Americans, hoping to reach a separate peace deal which would allow the Germans to concentrate all their forces on the Eastern Front. In the meantime, Ernst Kaltenbrunner becomes suspicious of Stierlitz, and orders Heinrich Müller to launch a covert investigation on him.
Stierlitz is ordered by Moscow to ascertain whether the Americans and the Germans have a backdoor channel and, if so, to foil any possible agreement. His mission is complicated when the house of his assistants, radio operators Erwin and Katherin Kinn, is bombed. Erwin is killed, and his pregnant wife is taken to a hospital, threatening to compromise Stierlitz. He recruits two new aides—Professor Pleischner, a former member of the German Resistance, and Pastor Schlag, a clergyman who disapproves of the regime. All the while, Stierlitz has to engage in a battle of wits with Müller, who seeks to expose him as an enemy agent. He must also maneuver between the opposing factions inside the Main Security Office, as different high-ranking officials vie for power.
After realizing Himmler and Schellenberg have sent Karl Wolff to negotiate with Allen Dulles in neutral Switzerland, Stierlitz—playing on the rivalries between the Nazi plenipotentiaries—succeeds in leaking the details of the negotiations, conducted under the code name Operation Sunrise Crossword, both to Hitler and to Stalin. The Soviets, now possessing evidence, demand to end those contacts and President Roosevelt must oblige them. Himmler narrowly convinces Hitler it was all merely an attempt to sow distrust between the Allies. On 24 March 1945, Stierlitz, who managed to clear all suspicions against him, returns to his duties. The Red Army is steadily approaching Berlin.
