"Evil Unbound", a new film depicting the horrors of the Imperial Japanese Army’s Unit 731 and its germ warfare programme, has hit cinemas across China and beyond. As the latest in a wave of patriotic films to find success at home, it sheds light on one of WWII’s darkest chapters – Unit 731, the covert military unit that conducted inhumane human experiments during the war. We take a deep dive into the historical reality behind the film, featuring testimonies from former Unit 731 members – never before seen in Europe – and expert insight from Dr. Andres Rodriguez of the University of Sydney.
