This epic docudrama by Koji Wakamatsu depicts the rise, in the late 1960s and early 1970s, of the far-left Japanese paramilitary group known as the United Red Army., The film portrays in harrowing fashion how the army disintegrated as they began to torture and murder their own members during training sessions in the mountains.
