Strange incidents start occurring, such as an event where a vessel that had disappeared in the Japan Sea turns up in the Pacific Ocean. Dr. Ochanomizu thinks that there could be a submarine canal right beneath Japan. So Atom goes in search of the canal, and encounters subterranean people on the ocean floor.
