The Interrogator Special: 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.
