Kuryu Kohei is a newcomer prosecutor from Aomori of the Tokyo Prosecutor's Office. Upon his transfer, he is immediately put in charge of a corruption case involving a congressman and an underwear theft. His new colleagues do not seem to put their trust in him because of his nonchalant attitude. A rumor seems to be going around the office involving Amamiya, Chief, and Egami.

A man falls to his death during a fight that involves a politician's son. As the prosecutor in charge, Kuryu investigates the case while his other work had to be delegated to his colleagues. Tired of his antics, they all complain. At the same time, Egami doesn't give up on Amamiya, and Shibayama continues his affair with Nakamura.

Amamiya and Egami drink at a bar while talking about relationships. They encounter a couple fighting over something. Drunk Amamiya confronts the couple and Kuryu who is nearby walks over to stop her from interfering with the man who is holding a knife. The man ends up wounding the woman on her wrist. The woman then sues the man for criminal injury. Meantime, the story unfolds as Kuryu and Amamiya discover that the woman is actually involved in a marriage fraud.

A female university student is murdered by her stalker. The suspect, Oyamada Shuji, is hospitalized but he soon flees, resulting in the risk of the Tokyo Prosecutor's Office losing face, and even Egami's job. Meanwhile, Shibayama gets headhunted by a law firm. In the midst of that, Kuryu investigates a dine and dash case.

Kuryu and Amamiya investigate an affair that resulted in the husband slashing the wife with a kitchen knife. Back in the office, an uproar is caused by a rumor of an affair of a detective, and Amamiya's sudden confession of having a boyfriend. Misuzu is unhappy about Shibayama's reaction to the affair rumors.

A judo practitioner, Yasuda, is prosecuted for stabbing and killing an off-duty patrol officer. Kuryu senses that something is fishy since it doesn't make sense for someone with a high rank in judo to carry a knife around. The president of a loan shark ring, Mr. Otagawa, is then arrested by the chief police after Yasuda admits that he is only following orders to turn himself in. How can Kuryu prove that Mr. Otagawa is responsible for the murder and not Yasuda?
