かつて迷い込んだ商店街で、えたいの知れない雰囲気と危険をはらんだ瞳で恵那（長澤まさみ）を惑わせた男。その人物こそが、大門副総理（山路和弘）の有力な支援者の長男・本城彰だという。あの男には何かある―。そう直感した恵那は拓朗（眞栄田郷敦）に調査を依頼。 連続猟奇殺人の犯人について、ある“仮説”を立てた拓朗は、再び八飛市で聞き込みを行い、最後に殺された中村優香と親しかった高岡ひかるにたどり着く。ひかるの携帯電話に残されていた写真が、拓朗をさらに突き動かすことになる。 事件の真相に近づこうと突き進み、興奮気味に報告をしてきた拓朗に対して、恵那の反応は妙に鈍かった。強いいら立ちを隠せない拓朗はついに、恵那に“本心“を問い詰めたが、返ってきた言葉は…。
수상하다는 에나의 말에 타쿠로는 혼죠 건설의 장남인 혼죠 아키라를 조사한다. 상점가에서 가게를 운영하던 그는 왜인지 동네 아주머니들에게 인기였다. 하지만 사사오카 기자는 핫토비산에서 살인사건이 일어나지 않은 시기에 혼죠 아키라가 일본에 없었음을 알아낸다. 피해자가 다니던 학교의 학생들을 탐문하던 타쿠로는 피해자와 친했던 한 여자아이를 만나게 된다.
A man who once misled Ena (Nagasawa Masami) with his mysterious atmosphere and dangerous eyes in a shopping street she wandered into. That man is Akira Honjo, the eldest son of a powerful supporter of Deputy Prime Minister Daimon (Kazuhiro Yamaji). There is something about that man. Ena has a hunch, and asks Takuro (Maeda Go Atsushi) to investigate. Takuro comes up with a "theory" about the perpetrator of a series of bizarre murders, and interviews people in Yahi City again, which leads him to Takaoka Hikaru, who was close to the last victim, Nakamura Yuka. A photograph left on Hikaru's mobile phone further motivates Takuro. Ena's reaction to Takuro, who has been pushing forward to get to the bottom of the case and excitedly reporting back to her, is strangely muted. Unable to hide his irritation, Takuro finally asks Ena about her "true feelings", but what does she say?
