It is 1944 and Reich Minister of Propaganda Joseph Goebbels narrowly escapes an assassination attempt on the way to Obersalzberg. It is whispered to him that his rival Heinrich Himmler is the mastermind and that he has also hidden a double of the propaganda minister. Goebbels sets off immediately. He meets his double, Harry Geduldig, in a mysterious fortress. There is a mix-up. The real Goebbels remains a prisoner in the fortress, while the fake one deceives the guards and escorts and frees his great love Grete Zipfel. At a party meeting in Nuremberg, the people cheer him on. But then the journey takes him into the lion's den: on the Obersalzberg he meets Hitler and finally "his" wife Magda. Harry risks everything to save Grete.
