A Polish nationalist is arrested after the Communist takeover of Poland following World War II and sent to a prison run on Soviet lines, where interrogators use psychological pressure rather than physical violence to break him into a confession. The account is drawn from the real experiences of a former inmate of a Moscow prison, and the film follows the isolation, sleep deprivation, and manipulation used to wear down his resistance over time. Produced by the National Security Council and the CIA in 1956, it is a Cold War information film rather than a neutral historical record, made to illustrate to American audiences how Communist interrogation techniques worked and why they were effective even without torture in the physical sense. The prisoner's refusal to sign a false confession is presented as the throughline of the story. Now in the public domain through the National Archives, it stands as both a case study in psychological coercion and a piece of period American propaganda.
