Polizeiruf 110 is a long-running German language detective television series. The first episode was broadcast 27 June 1971 in the German Democratic Republic, and after the dissolution of Fernsehen der DDR the series was picked up by ARD. It was originally created as a counterpart to the West German series Tatort, and quickly became a public favorite.

This story of the miller Florian, who gave all his money to the war against Napoleon, is loosely based on a true story. After the war, Florian's reimbursement is challenged, and he must also pay taxes on his destroyed mill. He resists the tax collectors and takes off to Vienna, where he intends to defend his rights. On the way, he rescues the Duchess of Guastalla from assault. She also wants to go to Vienna, as His Majesty Franz II is trying to contest an heir in her favor. With cunning, luck, and dagger, Florian fights his way through a slew of nobility and their secret police.
