In the Principality of Andorra, located in northern Spain, Japanese investor Naoki Kawashima (played by Shosuke Tanihara) is found dead abroad. He is the son of the police chief, and the scene is determined to be a homicide, which draws significant attention from Japan. The International Criminal Police Organization's Makoto Shinto (played by Hideaki Itto) and Counter-Terrorism Office's Kosaku Kuroda (played by Yuji Oda) jointly investigate the case. On the surface, it appears to be a typical case of murder during a home invasion, but Kuroda senses that there must be hidden secrets behind it based on the clues at the scene. The first discoverer of the crime scene, a bank employee named Yuka Shindo (played by Meisa Kuroki), who has a business relationship with Kawashima, seems to harbor deep, undisclosed secrets. As expected, attacks targeting Yuka follow one after another, and Kuroda and Shinto gradually close in on the truth of the incident... This film is the second feature film of the TV series 'Diplomat Kosaku Kuroda'.
