Former police officer Terahara Ken (Omori Nao) works for a private security firm. He is suddenly summoned back to Japan while on duty in Taiwan and ordered to protect Matsuoka Takanori (Takeda Tetsuya), the secretary general of the Democratic Party. On the other hand, public prosecutor Sakurai Satoko (Kuroki Hitomi), who was transferred to the Kochi District Public Prosecutors Office for a previous whistle-blowing incident, returns to the Special Investigation Department of the Tokyo District Public Prosecutors Office in a reshuffle by her former superior for the purpose of indicting a big shot. In the midst of this, a branch office of Tokyo’s Aoba Shinkin Bank is blown up and the bank’s armoured truck is attacked.
