LABORATORY OF THE DEVIL tells the story of Morishima, a young, idealistic doctor practicing in WWII Japan. Upon discovering Unit 731, a secret military prison in Manchuria, Morishima is horrified by the treatment of the captives, who are brutalized and subject to torturous experimentation. In the name of science, of course! There's only one solution for Morishima - he must liberate them all. Massacre Video proudly presents LABORATORY OF THE DEVIL, the controversial sequel to the notorious and disturbing MEN BEHIND THE SUN. This uncut, newly restored version is compiled from the Original Camera Negative, with video inserts for missing scenes. Only director. Godfrey Ho could conceive such a chilling tale.
