Taking its title from an archaic Japanese word meaning "ghost story," this anthology adapts four folk tales. A penniless samurai marries for money with tragic results. A man stranded in a blizzard is saved by Yuki the Snow Maiden, but his rescue comes at a cost. Blind musician Hoichi is forced to perform for an audience of ghosts. An author relates the story of a samurai who sees another warrior's reflection in his teacup.

The famous blue ruby is stolen in such an elaborate way, that only one villain can be suspected - Professor Moriarty. It is up to Sherlock Holmes to return it and, in the process, to turn a young pick-pocket on the right path. In the second part, Moriarty sets his sights even higher, stealing a top-secret submarine from the Navy. What does he need it for? Holmes is once again on the trail.
