Synopsis
It traces the atrocities of Unit 731’s biological and chemical warfare, reflects on history’s scars, and prays for humanity’s peace.
In 1992, Xiao Jin, a staff member at the Harbin 731 Museum, discovered incomplete records of this period of history while organizing historical materials. To uncover the truth, he embarked on a decades-long transnational journey of evidence gathering, gradually revealing the truth of that dark and long-buried era.
The story employs a dual timeline narrative, returning to Harbin during the Japanese invasion of China. Through the perspectives of several individuals involved, it profoundly exposes the brutal human experiments and inhumane atrocities committed by the Japanese Unit 731, condemning the anti-human nature of Japanese militarism and highlighting the resilient spirit of resistance of the Chinese people.
