In the made-up country of Alanien, King Alexander I has been overthrown while abroad. Now, he's in Vienna with his daughter, the city of his fondest memories since studying there as a boy. It doesn't take long for the charm of Vienna to work its magic on the former king: he quickly comes to terms with the new situation and is able to enjoy the Austrian capital sans all the ceremony and trappings which would otherwise accompany him on a state visit. The princess is content with preparing herself for a career as a pianist concert, while the former king takes a job as a chauffeur in the embassy of the country he once ruled. The revolutionaries are shocked; and his days in Vienna are numbered.
Albin Skoda embodies a frantic Adolf Hitler in his last days, scrambling to keep the Third Reich alive as morale within the bunker wanes and Berlin is encircled by enemy troops. Based on Michael A. Musmanno's book Ten Days to Die, Oscar Werner costars as fictional Nazi Hauptmann Wüst, a disillusioned middleman.
