With World War II nearing its end, the Aryan geneticist and frigid lieutenant of the SS, Fräulein Ellen Kratsch, gives her all to create the latest secret weapon of the Third Reich. And, as the Nazis comb the villages scattered in the mountainous region of Canavese in Italy for surviving Partisan movements, unheard-of chemicals transform perverse Dr Kratsch's caged specimen into a brutal, sex-crazed abomination attracted by the scent of intense fear. Now, to mark a turn of the tide in the war, Dr Kratsch will not hesitate to provide her precious hybrid with fresh batches of helpless naked women. Is there an escape from the clutches of the savage beast in heat?
