Kaiser's Finish is a 1918 American silent World War I drama film, directed by John Joseph Harvey.
In pre-World War I Germany, Kaiser Wilhelm (Louis Dean) fathers a number of illegitimate children and sends them to various parts of the world to be reared by his loyal agents.
When the United States declares war on Germany, Robert expresses his earnest desire to enlist in the American army, much to the delight of his patriotic sister Emily (Claire Whitney).
Before he can do so, however, Strumpf tells Robert the secret of his parentage, believing that the young man now will be eager to fight for Germany's cause.
Robert feigns enthusiasm but secretly offers his services to the U.S. government, and with the passport provided him by the Pan-German league, he goes to Germany and kills the crown prince (also played by Schenck).
