A desperate search for a missing MI6 colleague and the microfilm he possesses leads Professor Katrin Nissen deep into the maelstrom of Nazi-controlled Berlin. Impulsive and reckless, Dieter Weiss may have pushed his luck too far and taken one chance too many. Against all odds, Katrin has only one week to find him.

Posing as a research scientist sympathetic to the Nazis, Katrin attends a conference organized by Heinrich Himmler. The conference will showcase the Nazis' dark plans to redesign nature and will become the birthing ground of the Holocaust-a cost far greater than Katrin is willing to accept.

Weiss's sister, Kristine Trautmann, a staff photographer for Himmler, is also at the conference. While Kristine may provide the key to Dieter's whereabouts, she has her own secrets, and should Himmler discover the truth, it will cost her life.

Against a backdrop of a political agenda so bizarre as to seem impossible, Katrin discovers that the Nazis aren't the only ones to fear. A serial killer stalks the university halls. Armed with her wits and her trusty stiletto, Katrin finds herself in the crosshairs of danger in the fight of her life.
