Kurashina (Manama Hamada), a senior university student and scientist of Zenigata (Ryohei Suzuki), was murdered. Zenigata pleaded with the administrative officer, Ikkei Watanabe, to participate in the investigation and began an investigation with Kunikida (Takahiro Miura). Around the same time, Abe (Atsuro Watanabe) of the Ministry of Public Security was also investigating the incident internally. Soon, a man who was attached to Kurashina's lover, Miki (Ashina Hoshi), emerged as a suspect, but the man was hit by a car and died. The unconvincing money form arrives at one contradiction from the investigation material, and it comes out to a certain action.
