Guided by a map thrown in by someone, the Akechi family and detective team visit the Boso Peninsula. Staying at Akechi's villa, the group heads to the waters off an uninhabited island known as “Devil's Island.“ There, they are working to salvage the Ashibiki Maru, a ship that sank with the Shogunate's military funds aboard, but the work is proving difficult due to a mysterious monster. Akechi and Kobayashi, who entered the sea in place of the frightened divers, encounter a monster on the seabed. They return to land and try to find out what it is, when the monster comes ashore and attacks them.
