In the distant Showa era, throughout more than sixty years of history, numerous grim incidents were buried in darkness. In a remote seaside village, young women fell victim one after another to a vicious criminal who escaped over the mountains. Meanwhile, on an island where a female bandit gang was exiled, the prisoners suffered unimaginable torture and assault at the hands of their guards. This is a dark chapter of criminal history that must never be repeated, a tale of terror and horror still passed down to this day.
