At the end of World War Two, American intelligence agencies faced a problem: some of the scientists, engineers, and operatives with the most valuable knowledge of German weapons programs and Soviet intelligence networks were also implicated in Nazi war crimes. This film traces how the CIA and its wartime predecessors weighed that trade-off, recruiting former Nazis for their technical expertise and Cold War utility while trying to keep their pasts quiet. It lays out the reasoning intelligence officials used to justify these arrangements, the risk that a recruit's history could surface and become a liability, and the long-term consequences once some of these alliances came to light decades later. Rather than a single case study, the film works through the pattern across the early Cold War, treating each recruitment as a test of how far national security thinking could stretch to accommodate men who should, by any other standard, have been prosecuted.
