A few hours in the life of empress Sisi; a summer night at Gödöllö. A game with operetta and melodrama; a grotesque with much colour, music, dancing, and bloodshed.

After a wonderful time in Hungary Sissi falls extremely ill and must retreat to a Mediterranean climate to rest. The young empress’ mother takes her from Austria to recover in Madeira.

Sissi is now the empress of Austria and attempts to learn etiquette. While she is busy being empress she also has to deal with her difficult new mother-in-law, while the arch-duchess Sophie is trying to tell the emperor how to rule and also Sissi how to be a mother.

The young Bavarian princess Elisabeth, who all call Sissi, goes with her mother and older sister Néné to Austria where Néné will be wed to an emperor named Franz Joseph, Yet unexpectedly Franz runs into Sissi while out fishing and they fall in love.
