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.
This movie takes place during the premiere of Mozart's Die Zauberfloete (The Magic Flute). Not really depicting his entire life and loves, much of this is fictionalized scatology. Although not without basis in fact, Mozart has attained a somewhat colorful reputation and this is really just more of the same. The music is a joy, but the movie bogs down in titillation. Mozart's last days were lived in poverty and disgrace--stemming chiefly from his embracing of the Freemason stance, which was essentially a heresy in Austria and the rest of Europe at that time. None of this is depicted and even a satyr could not sustain the lifestyle Mozart has been portrayed as having here. Still, this is an interesting movie and worth a listen to.
A long time-span of Austrian history (from the late 19th century to the years after world war II) is reflected in the ups and downs of a family of piano-makers in Vienna.
