Yukihira Natsumi works as a police officer at the murder squad of Tokyo. She can differentiate felonies only into black and white but nothing in between ever since her father was murdered, so her guiding principle is to punish criminals by whatever legal action it takes. Beside Yukihira's success at work, her private life is a mess after creating a public scandal at a hostage-taking scene.

After another risky action taken at a hostage-site, her boss assigns her a new partner, Ando Kazuyuki, a rookie cop, who is supposed to look after her.

This drama follows Yukihira and Ando solving a serial murder case.
