Europe, in the spring of 1940. After the lightning victory over Poland, Hitler's Wehrmacht drew up plans of attack for the overthrow of Western and Northern Europe. Several high-ranking officers fear that Hitler's excessive policy of conquest will ultimately plunge Germany into the abyss and therefore intend to contact Great Britain through diplomatic channels. After careful consideration, these officers from the management level of the Wehrmacht selected the journalist Robert Golder, who was critical of the regime, in order to establish contacts with the enemy. But also the other side in the form of Reichsführer SS Heinrich Himmler has not remained inactive and tries to dig the nest of resistance. Due to a warning from the waiter in his favorite pub, Golder barely escaped being arrested by the Gestapo but was subsequently overwhelmed and kidnapped. But it is not Himmler's henchmen who kidnapped Golder. Rather, it is the resistance group behind it who want to use Golder as a messenger. He is supposed to convey Hitler's plans for the upcoming campaign in the West to a person of trust in the Vatican so that countermeasures can be initiated in the affected countries. This is to prevent a further escalation of the war.

The plan of the opposing Wehrmacht officers is to be able to hold talks with the British and French after a planned overthrow of Hitler in order to conclude a separate peace. Robert Golder is sent to Rome with the secret plans for the western campaign to a respected member of the Catholic Church. Himmler cannot prevent Golder from leaving the empire for Italy with a forged passport. But he notifies his most loyal representative on-site, the senior SS-Mann Hoffmann. This brawny guy has set up a regime of terror in the Italian capital that is disgusted by the ally in the form of the Roman police prefect Ferrari. While Golder intends to visit his contact, the other side is not idle, because Golder's opponents still have an ace up their sleeve: the equally pretty and dangerous top agent Tilla Turner, who is assigned to the journalist on a secret mission. But opponents eventually become confidants when Golder and Tilla fall in love. Now both are in mortal danger...
