This time, we will take a closer look at the truth of the murder of the president of a jewelry store in Tokyo, set in the magnificent scenery of Echizen, including Tojinbo, a strange victory in Fukui Prefecture. Guest appearance is Okochi Nanako as Nomura Hiromi, the mistress of the president of the jewelry store, and Kurasawa Kanami, the bamboo doll craftsman who holds the key to solving the case, will play two roles.

Inspector Totsugawa and Detective Kamei challenge the mystery of serial murder that originated in the burning and sinking of a huge tanker in the Indian Ocean. The story is a large-scale development where the stage moves from the Indian Ocean to Brazil, Ikaho Onsen, and Sendai. Eventually, a former captain of a tanker, who seems to hold the key to the case, appears on the investigation line. When Totsugawa notices the plan of the former captain, the existence of a huge evil that shakes the political and business world becomes clear. Watari Tetsuya plays Okudaira, a former tanker captain who is an important figure in the story. Watase agreed with Watase's wish to help with the 50th commemorative work, and the brothers co-starred.
