Five years after leaving Josai bureau, Kuryu Kohei, who has been working in Sapporo, Hokkaido, is transferred to Nijigaura, Yamaguchi (a fictitious town, its real name is Nijigahama), a quiet place on the seaside where he arrives precisely when the first murder in eleven years has been committed. Soon, Takita Akihiko, the most beloved and influent person of the town, is suspected and Kuryu has to deal with this problem, as the other members are too frightened to take any action.
