In 12th-century Japan, swordsman Kurou escapes ghastly pursuers into a deep forest with his servant Benkei. Seeking shelter, the two find themselves within the secluded abode of the mysterious and beautiful Kuromitsu. While they are warmly accepted, the men are warned to never enter Kuromitsu's room.
