Five years have passed since Kuryu Kohei's transfer from Tokyo to Ishigaki, and then to Sapporo. He ends up in a small town of Nijigaura in Yamaguchi Prefecture. There, he investigates a murder case involving a local enterprise, Kamoi Group, and the people related to it. Everyone in town thinks he's innocent except Kuryu, whose unorthodox investigation methods perplex not only the townspeople, but his colleagues as well.

Yukiko Makabe is the only female interrogator in a department full of men. Their job is to question suspects immediately after a crime, using interrogation skills and psycho-analysis to solve crimes. As the only female in the department, Yukiko has a different perspective and style from her colleagues. This brings her success in her interrogations of suspects, but Yukiko continues to be troubled by an unsolved cold case from years ago.
