Due to the mistakes of the case-handlers, the kidnapper's crucial phone call was not recorded. The relevant personnel took responsibility, while the police high-level officials regarded it as a forbidden area and did not mention it. While struggling with the media, Yoshinobu Mikami (played by Koichi Sato) tried his best to break the police's stereotype and conduct an in-depth investigation of the case of that year. At this time, the daughter of a sporting goods store owner (played by Naoto Ogata) was kidnapped, and the relevant methods were exactly the same as the "64 case"! Could it be that the murderer overturned the case again? Mikami and his peers worked hard, and the police also invested a lot of manpower to investigate, but they found an incredible secret. The withdrawal of Emperor Showa from the stage of history attracted the attention of countless people. However, even if buried by the dust of time, some things and some people will eventually be remembered for a long time... This film is adapted from the mystery novel of the same name by Yokoyama Hideo.
