After Japan’s defeat in 1945, Unit 731’s scientists escaped prosecution through a covert deal with the United States, trading biological warfare research for immunity. The agreement helped bury one of the war’s most disturbing secrets for decades.

Families of Allied POWs search for answers about unexplained injections and illnesses that followed captivity. Through personal archives, declassified documents and expert testimony, descendants confront the possibility that secret tests may have taken place, and the lasting impact on their families.

Former Unit 731 member Hideo Shimizu returns to Harbin for the first time since the war. Standing inside the ruins where human experiments were once conducted, Shimizu reflects on the silence that followed and the responsibility of those who witnessed it.

Episode 2 reveals how political deals and buried evidence allowed one of wartime’s darkest secrets to go unpunished, leaving families still searching for the truth.
