The film unfolds in two axes, although without the usual use of flashbacks. The first one, which is loosely based on the 1997 murder of Yasuko Watanabe, takes place in the present. Detective Yoshida investigates a murder incident in Maruyama-cho, a love district in Tokyo, where a dismembered body has been found in an abandoned building. The missing parts have been replaced with the matching ones from a plastic doll.
The second axis, which takes place before the first, focuses on Izumi, a dedicated spouse and housewife, who is married to a famous erotic novelist, Yukio Kikuchi. He spends most of his day outside his home, trying to find inspiration for his books, while she tries to brew the perfect tea for him and to place his slippers the appropriate way.
