Chiba Prefecture, Japan. Acting on the advice of an anonymous note, Takuro Yamashita (Kōji Yakusho) returns home early one night to find his wife in bed with another man. He kills her and then turns himself in to the police. After being released from prison, he opens a barber shop and brings along a pet eel which he talks to while mostly ignoring conversation with others. He helps save Keiko Hattori (Misa Shimizu) from a suicide attempt, resulting in her working at the shop. She starts developing romantic feelings for him, but he acts nonchalant and refuses the bentoes she prepares for him when he goes eel-hunting with the fisherman Jukichi Takada. Takuro recognizes the local garbageman from prison and the garbageman starts to stalk Takuro and Keiko, believing that Takuro isn't repentant enough for his crimes. He attempts to rape Keiko and leaves a letter revealing Takuro's past on the door of his barber shop, but it is removed by Takada. Keiko finds out that she is pregnant with the baby of Eiji Dojima (Tomorowo Taguchi), a loan shark, and that it is too late for an abortion. One night the garbageman goes to Takuro's shop and lectures him, accusing him of killing his wife out of jealousy. The two get into an altercation and Takuro fends him off. Keiko goes back to her old company, where she is the vice-president, and retrieves her mother's bankbook. This results in Dojima angrily going to the barber shop, along with henchman, and accusing her of theft since he was planning to reinvest the funds into his business. Dojima's group and Keiko's fight, with the false revelation that Keiko is pregnant with Takuro's child. The police find that Keiko's mother never signed power of attorney papers for Dojima, but a parole violation meeting for Takuro causes him to be sent back to prison for a year. Takuro lets his eel go and accepts a boxed lunch from Keiko, who promises to wait for him with her baby.
