Student Hans is so appalled by decadent Berlin and the schemes of the Communist Party that he inspires the Nazi cohorts of his fellow storm troopers to actively fight the Communists who in turn conspire to assassinate him.

This Nazi propaganda film purports to show the story of a Nazi Storm Trooper named Horst Wessel--here called "Hans Westmar"--who took part in street brawls and assassinations in Berlin in the 1920s and 1930s against Communists and other opponents of the Nazis, and was killed by Communists not long before this film came out.—A.Nonymous
