A man arrives in the city upon news of a potential terrorist strike in Italy. He is Japanese foreign diplomat, Kosaku Kuroda, and he’s here under orders of his supervisor at the Foreign Ministry, Hiroshi Kataoka (Kiichi Nakai), to aid in the safeguarding of Japanese citizens. Kuroda’s main contacts at the Japanese embassy consist of Ambassador Kikuhara, Counselor Nishino, and fellow diplomatic envoys Haba and Tanimoto. All are busy preparing for the visit of Japanese Foreign Minister Kawagoe due to arrive for the high-profile G8 foreign minister’s meeting. Meanwhile, somewhere on the festively-lit streets of the city, a young Japanese girl has suddenly gone missing. Is it an abduction simply for ransom? Or could it be a prelude to terror?

While the Japanese government is trying to crack down on international crime organizations' money laundering in tax havens, the Chief of Police's son is found dead in a hotel in France.
