Friedrich is a wealthy, handsome German soldier fighting in World War II. His unit is stationed in Poland and occupies the estate of Countess Elzbieta. Forced to remain in her presence, Friedrich begins to pursue Elzbieta out of boredom.

“Death is my Trade” centers on the life of Rudolph Höss, the commandant of Auschwitz II-Birkenau for the majority of its existence. The main character's name in the film is Franz Lang. This name change was deliberate to ensure that the character is not automatically viewed as being some sort of villain or demon. Franz is an average German kid growing up during World War I. The film follows Franz as he grows up and becomes a hard, efficient, organized worker who eventually joins the National Socialist party in Germany. Impressionable young Franz takes orders as one of the utmost points of honor and duty, so when he is eventually asked by Heinrich Himmler to become commandant of the largest extermination camp built during WWII he barely hesitates to consider how heavy such a burden will be.
