In the final days of World War II, American spy Michael Rogan (Edward Albert Jr.) is taken prisoner, along with his wife and comrades from the French underground. A sadistic six-man interrogation team fails to get any information out of Rogan, and brutally murder his wife and fellow conspirators, shoot him, and leave him for dead. After the war, Rogan sets out on a mission of bloodshed and terror that takes him across Europe. Haunted, wounded, and relentlessly driven by his hatred and his memory, Rogan avenges the senseless murders, one by one. The leader of the interrogating team and Rogan's ultimate target is Von Osten (Rex Harrison), now a major political force in post-war Germany. Von Osten is on the verge of gaining the Chancellery and becoming a puppet for the Americans. Rogan carefully stalks his prey, dodging American agents and tensely awaiting his chance. In the final confrontation, Rogan must face both his memory and his tormentor, but it is Von Osten that must stare into the steely eyes of hatred and look justice square in the face.
