In a run-down South American town, four men are paid to drive trucks loaded with nitroglycerin into the jungle through to the oil field. Friendships are tested and rivalries develop as they embark upon the perilous journey.

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.

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.

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.

As a parting shot, fired reporter Ann Mitchell prints a fake letter from unemployed "John Doe," who threatens suicide in protest of social ills. The paper is forced to rehire Ann and hires John Willoughby to impersonate "Doe." Ann and her bosses cynically milk the story for all it's worth, until the made-up "John Doe" philosophy starts a whole political movement.
