Wataru (Takashi Sorimachi) goes back to the Tokyo Metropolitan Police Department after finishing training at the police academy, but he is assigned to the public relations division and not to investigation department. Meanwhile, Hatsue Kurusu goes to the #1 investigation division and claims to have killed Futoshi Miyata. Three days ago, Futoshi’s dead body was found at an irrigation channel and the police concluded that he died by accidental drowning. Hatsue Kurusu asks to be punished for his actions. Ukyo (Yutaka Mizutani) takes an interest in Hatsue’s appeal and begins an investigation by himself.
