Kojak: The Belarus File (1985)

Lieutenant Theo Kojak of the New York Police Department is investigating the suspicious murder of several men of Byelorussian origin. At first, the murders do not seem to be connected. However, Kojak discovers the fact that all these murdered men were of similar age, knew one another and immigrated to the USA shortly after the end of World War Two. Kojak starts believing that all these murders are connected and are the work of a serial killer. Even so, Kojak cannot find a motive for these killings. The victims were respectable citizens, liked by everybody and they had no known enemies. When Kojak intensifies his investigation, the U.S. State Department orders him, through his superiors, to drop the case. Kojak visits the U.S. State Department hoping to access the immigration files of the victims but he's stonewalled by the Feds. Nevertheless, Kojak finds a sympathetic female officer at the State Department willing to help him dig through the old files concerning these Byelorussian immigrants. That's when things take a different turn. Kojak stumbles upon information concerning former Nazis who came to America after the war, about their past war crimes and regarding U.S. Government's involvement in safe-harboring some of these individuals in an effort to use them against the Soviet Union during the Cold War.
