A woman is found strangled to death in an apartment in Tokyo’s Katsushika Ward.
The victim is Michiko Oshitani, a resident of Shiga Prefecture who worked for a home cleaning company.
What’s more, the occupant of the apartment where the murder took place, Mutsuo Koshikawa, has gone missing.
Matsumiya (Junpei Mizobata) and his fellow detectives of the Tokyo Metropolitan Police’s Investigation Section 1 begin investigating, but hit a brick wall when they fail to find any links between Oshitani and Koshikawa.
Why was Oshitani, who lived in Shiga, killed in Tokyo?
Eventually, the detectives’ inquiries lead them to a theater director named Hiromi Asai (Nanako Matsushima).
They learn that Oshitani came to Tokyo to visit her former classmate Asai, but again come up with nothing when searching for connections between Asai and Koshikawa, and their investigation grinds to a halt.
Matsumiya has a hunch that a charred corpse found nearby the murder scene may have some relevance to the case, and subsequently discovers an item among the victim’s belongings with the names of Nihonbashi’s 12 bridges written on it.
