Concha flies from his natal Rio to Germany to help his loved one, who has been caught after finding some diamonds in a mine already registered by a company. Amongst them is the impressive one which thanks to her will be known as The Star from Rio. She finds herself staying at the manager's home hired as a dancer to present the diamond at a fashion show. Then the lights go suddenly out.

German chancellor Otto von Bismarck promises the dying emperor Wilhelm I. to be loyal to his grandson. But the gap between young Kaiser Wilhelm II. and old Bismarck is rapidly widening. It soon appears that an era is coming to an end.
