  ## Plot
  
  The only daughter of widower Nagamine Shigeki (Terao Akira), an architect, is found dead. A few days later, Nagamine gets an anonymous phone call giving him the names and address of the perpetrators. Upon entering the said apartment, Nagamine finds a snuff video in which two young men rape and kill his daughter. He waits for the murderer to return home, and stabs him to death.
  
  Nagamine then heads out of the city to Nagano to find the other youth in the video, writing a long letter to the police about why he killed the boy in the apartment, and his intention to do the same to the other murderer when he finds him. In the letter he specifically cites the Japanese laws that fail to punish under-age criminals. This letter also is sent to the press, and is published in newspapers across the country.
  
  While in Nagano, Nagamine tracks down the murderer. During his lengthy journey, he touches a number of people with varying opinions about the validity of his quest, including the Tokyo policemen investigating his case, and a father-daughter family unit who own an inn in which he takes refuge.
