During the German occupation of a small Polish town, Franciszek Kłos, a lowly local policeman, will stop at nothing to become a Volksdeutsche. Eager to prove his loyalty, he zealously carries out the occupiers' orders. What begins as administrative compliance soon escalates when he commits his first murder of a fellow Pole. Condemned to death by the Polish underground, Kłos outwardly shrugs off the sentence while quietly drowning his growing fear in alcohol. As his inhibitions crumble, he descends deeper into violence—participating in the roundup and execution of hidden Jews, and earning a reputation for brutality even among the SS.
