A story set in a period where the Japanese are ruling Korea and using their military might to expand into China, whilst the second world war has not yet started in Europe. One man attempts to bring to the attention of the world the shocking human experiments that a certain section of the Japanese army is conducting on fellow humans. Thousands of Chinese citizens, Russian prisoners, Koreans, pregnant women and children are being murdered by the evil Unit 731 that hides behind the official name of 'Epidemic Prevention and Water Purification Department of the Kwantung Army'. The man in question is called Thomas who has been working across Asia as a agent for the Gestapo for over one year as the Germans and Japanese develop closer relationships.
