"During the shut down and destruction of the Japanese test camp Unit 731 in Manchuria, a soldier becomes infected with a virus developed during the camp's testing and risks spreading it into Japan on the train ride home." The third one is more low budget war flick then torture porn but it does reuse the shocking scenes from the last two. I found it in it's entirety with English subtitles but it has Spanish subtitles over that so its a mess to watch but if you wanna see it, its below.
It's a mess to watch and read!
