Prince Klemens von Metternich orders Friedrich Gentz, one of his aides, to keep the Duke of Reichstadt---Napoleon Francois Joseph Charles---son of Napoleon and heir to the French throne, from thinking about French politics. Gentz enlists the help of ballerina Fanny Elsser, all the rage in several European capitals, to keep the Duke distracted.

After her husband dies, a German woman who gave up her infant for adoption to emigrate to America returns to Germany, discovering that her child is being raised by a married orchestra conductor.
