A stabbed body is found in a park in Hachioji. The victim is a man named Oshimi who was wanted for the murder of his ex-girlfriend 29 years ago and has been on the run. The statute of limitations has expired, but the First Investigation Division begins an investigation, believing that someone connected to the 29-year-old incident is involved.
Meanwhile, Ukyo (Yutaka Mizutani) receives a call from Miura, a former member of the First Investigation Division. After a brief reunion with Kaoru (Yasufumi Terawaki), Miura approaches him with an unexpected request.
Miura was in charge of dealing with the surviving family members of the incident 29 years ago, and is troubled by the thought that Tsunekawa (Kamio Yu), who was the victim's fiance, had tracked down Oshimi and committed the crime 29 years later.
Ukyo and Kaoru, understanding his heartfelt feelings, begin to take action and ask around at the supermarket where Tsunekawa works, looking for clues. They learn that Oshimi had recently shown up at the store and had been arguing with a part-time female employee. Ukyo and Kaoru ask the woman directly about the situation, but it seems she has her own problems. The events of 29 years ago and the present intertwine in a complex web of events, and the shocking truth is revealed at the end of this sad tale of revenge...
