This film explores a side of world history that is largely unknown to the Western World. Documenting the development of WWII from the perspective of the Far Eastern Front, the story of the gruesome human research center, UNIT 731, is also revealed. For centuries Japan attempted to annex Manchuria, a vast land in the Northeast of China. In 1931 they succeeded and immediately established the puppet state of Manchukuo, where they began human experimentation in an effort to create weapons of mass destruction for use in global warfare. In 1937 Imperial Japan declared full-scale war on China, and like its AXIS-partner, Nazi Germany, committed some of the most horrific war crimes of WWII. To this day, the impact of Imperial Japanese war crimes continues to affect the people of China and many other Asian nations that suffered under their wartime policies.
