A former TV presenter is murdered. On the same day, two police officers from the Metropolitan police Special Mission Task Force, Sugishita Ukyo (Yutaka Mizutani) and Kameyama Kaoru (Yasufumi Terawaki), are guarding a female Diet member, Katayama Hinako (Yoshino Kimura). The pair identifies explosives and saves her life. From the clues left at the scene, Sugishita builds up his case and finds a connection between the murder of the TV presenter and the attempted murder of the Diet member. During a painstaking investigation, the savage murder case of a young overseas volunteer five years earlier emerges in the background, and the pair prevents indiscriminate murder at the Tokyo Big City Marathon event by suppressing the perpetrator.
