'Philosophy Of A Knife' tells the shocking true story of the infamous Unit 731, the covert biological and chemical warfare research and development unit of the Imperial Japanese Army.  The film is a complete history of the unit from its beginnings in the 1930s to its demise in 1945, and the subsequent trials in Khabarovsk, USSR, of the many doctors and soldiers responsible for some of the most notorious war crimes ever perpetrated.  Previously unknown evidence is revealed by an eyewitness to the awful events at the facility, former doctor and military translator, Anatoly Protasov.  Part documentary and part feature, the story unfolds from the perspective of a young Japanese nurse who is witness to the many horrors, and a young Japanese officer who is torn between his sincere convictions that he is serving a greater purpose, using them as guinea pigs in this shocking tale of barbarity.  Philosophy of a knife is truly one of the most violent, brutal and harrowing movies ever made, and is all the more terrifying for the fact that it depicts events that mirror the awful truth!
