Assistant Inspector Himekawa Reiko rose from the non-career track to become the only female section chief in the Tenth Homicide Section of the Metropolitan Police’s First Investigative Division. Director Hashizume has been keeping tabs on her because of her daring investigation methods. Team Himekawa is made up of dutiful subordinates Kikuta Kazuo and Ishikura Tatsumo, as well as the diligent but withdrawn Hayama Noriyuki and newcomer Yuda Kohei. They proceed with investigations while fighting against Teams Kusaka and Katsumata. Although Reiko has personal problems and past trauma, she does not bring this to the workplace. She tackles cases head-on and closes in on the truth with her sharp instincts. ~~ Adapted from the novel "Strawberry Night (ストロベリーナイト)" by Honda Tetsuya (誉田哲也).
