Set in Tokyo, Japan during the 1950's.

Tamotsu (Gou Ayano) is suspected of murdering his actress wife Shizuka Harada (Rina Ohta). He flees to Taiwan and commits suicide. Tamotsu’s friend Banji Masuzawa (Tadanobu Asano) works as a private detective. Banji has doubts about Tamotsu’s death, but the case is covered up by powerful media mogul Heizo Harada (Akira Emoto).

Banji is then involved in another case involving the neighbors of the Harada family. He encounters drunk novelist Joji Kamiido (Arata Furuta), a publish company editor (Tomorowo Taguchi) and finally a beautiful woman Aiko (Koyuki) who holds the key to case. As it looks likes Banji has solved the case, something unexpected occurs.
