Unit 731: Did the Emperor Know? (1985)

Among the worst of the many atrocities committed during World War II were the germ warfare experiments conducted by Japanese doctors. The history of germ warfare unit, code-named Unit 731, was for half a century shrouded in mystery. Set up in 1935 by brilliant bacteriologist, Shiro Ishii, in a remote, high-security headquarters in a village in Japanese-occupied Manchuria, the unit was where Japanese soldier-scientists carried out freezing, ballistics and other experiments on Russian, Chinese, American, British and Australian prisoners. Ishii's aim was to make a biological weapon that would win the war for Japan. But unlike his Nazi counterpart, Josef Mengele, Ishii had no reason to take refuge in the jungles of South America at the end of the War. For he and his colleagues pulled off the most incredible deal with their erstwhile enemies.
