Divorce talks by Takayuki (Tomomi Maruyama) have begun. Her partner lawyer, Yoko Tachihara (Mami Kurosaka), blames Honjo (Kiichi Nakai) for using her dirty hands to hunt down her wife. Honjo and Ninomiya (Yuki Izumisawa), who proceed with the operation according to the scenario, are horrified to hear the conversation between the couple in the closed room of Takayuki. It was a creepy one, 'Have you ever seen a corpse with a messed up head?' A lot of information was sent to the security camera video that Kanako (Yuki Matsushita) spread on the net. Naoto (Takahiro Miura), who is frightened that it is only a matter of time, decides to move overseas as instructed by Katagiri (Kenjiro Ishimaru). Honjo and Kanako regret to say goodbye and eat together. Naoto suffers from guilt every time the name of Ryosuke (Minato Masagaki) who died appears in a peaceful conversation. On the other hand, Honjo is appalled by himself who doesn't even understand Ryosuke's topic. And he begins to leave words to Haruka (Yuka) just in case that day comes. Meanwhile, Naoto received an email from an unknown sender. It was also sent to Kanako. There is a sentence saying 'I know the criminal' ...!

Naoto (Takahiro Miura) who appears in the police to atone for his crimes without running away. However, it was Mikami (Takeshi Ohnishi) who was there. Mikami, who is colluding with Katagiri (Kenjiro Ishimaru), refuses to take it seriously, and Naoto, who is despaired, dazzles his whereabouts. On the other hand, Honjo (Kiichi Nakai) declares war on Katagiri and leaves the office. Ninomiya (Yuki Izumisawa) and Hatsuka (Mio Imada) follow Honjo. Honjo et al., Who investigate Katagiri, find that Katagiri was working at the prosecutor's office, which was in charge of the case of Mikuriya (Kenji Mizuhashi) at that time. It must not be a coincidence that Honjo and Katagiri, who were involved in the same incident and the same accident, worked in the same office ... I go to bow my head to let him. Ninomiya and Hatsuka go to the scene of the case in Karuizawa to investigate in detail in order to pass the request for retrial. Katagiri, who is wary of such movements, rumors on the net that Honjo is Alzheimer's disease. The world became a big fuss, and the press flooded into families such as Haruka (Yuka), Kazuya (Shu Miyazawa), and Hinata (Miyuko Ochii). Honjo was forced into a difficult situation ...!
