Seriál sleduje příběh rozmanité sebranky lovců nacistů v New Yorku v roce 1977. Lovci, jak se jim říká, zjistili, že ve společnosti žijí stovky vysoce postavených nacistických úředníků, kteří osnují vytvoření Čtvrté říše ve Spojených státech. Vybraný tým Lovců se tak vydává na krvavý úkol vykonat na nich spravedlnost a zmařit jejich nové genocidní plány.

Shortly after the end of the Second World War: In 1945 and 1946, the men of the British "War Crimes Investigation Unit" drove through northern Germany on the hunt for Nazi criminals. One of them is Captain Anton Walter Freud, the grandson of Sigmund Freud, the founder of psychoanalysis. Anton Walter Freud fled to London with his family from the Nazis in 1938. Now an intelligence officer, he's back to track down killers on Allied wanted lists: hitmen in pinstripes, brutal SS henchmen, and ruthless doctors who conducted medical experiments even on children. The soldiers who witnessed the liberation of the Bergen-Belsen concentration camp months earlier are not squeamish about it. 24-year-old Freud is a free spirit known for his unorthodox methods. He knows how to make war criminals talk. So he comes across a crime that has hardly been known before, the murder of 20 children in Hamburg in the last days of the war.
