The story of the second season will begin with the plot of the last episode of the previous season. The "Special Crime Countermeasures Office" of the Metropolitan Police Department's First Investigation Division was forced to disband. The office director Eriko Osawa (played by Yuki Amami) resigned and prepared to leave Narita Airport to return to the United States. However, while waiting at the airport, she received a call from Nodachi Shinjiro (played by Yutaka Takenouchi). Senior police officer Kenzo Kurohara will become the next sniper target of the anti-government organization "Black Moon", and an important member of "Black Moon" Ryuhei Takakura escaped during the escort. Although Eriko and the members of the Countermeasures Office rushed to the scene, Kurohara was still shot and the criminal escaped. Kurohara, who was seriously injured, was forced to resign. In order to take responsibility, the Countermeasures Office was disbanded again, and Eriko went to the United States. Two years later, Nodachi, who became a counselor, took over an important case as an opportunity to revive the Countermeasures Office. Can this motley crew of Makoto Kimoto (Erika Toda), Katagiri Takuma (Tetsuji Tamayama), Hanagata Ippei (Junpei Mizobata), Yamamura Keisuke (Yoichi Nukumizu) and Iwai Zenji (Tomoji Kobayashi) gather together again to work for Eriko and the Countermeasures Office? And can Nodachi still convince Eriko to take on the role of the office director this time?
