Hotshot Nagase Saichi is Tosaka Real Estate’s top realtor. He lies through his teeth and will stop at nothing to seal a deal. One day, he disturbs a monument located at a construction site.

Amagi Yu is a slightly eccentric detective who has been assigned to the Twelfth Section of the Tokyo Metropolitan Police Department’s First Investigative Division from the Lost and Found Centre. The Twelfth Section is called the “graveyard of detectives” and ridiculed as the “banishment room where hardened detectives who cannot be fired are sent”. Its assembled detectives Samura Kosuke, Yamashita Takumi, Nagasawa Keita, Mizutani Tamaki and Katagiri Masatoshi are elite and yet oddballs. Amagi appears fixated with time which seems to have no relation with a case. Raising questions about the timelines of the perpetrator and victim derived from the estimated time of death, time of crime, time of alibi and time limit, he searches for the meaning of “blank time” which arises from this. He obsesses over the weight of every minute and second of time because of some incident.

Hanzawa Naoki works as a loan manager at the Osaka Nishi branch of Tokyo Central Bank. One day, Hanzawa makes a loan contract for 500 million yen with Nishi Osaka Steel Company. Hanzawa didn't want to approve the loan, but he had to due to the branch manager's order. Nishi Osaka Steel Company seems financially stable, but the company actually hides massive amounts of debt through fraudulent accounts. The company is caught. Three months later, Nishi Osaka Steel Company goes bankrupt. The bank's branch manager is Asano. He is an ambitious man and tries to shift the blame to Hanzawa. Hanzawa then attends an inquiry about the loan failure at the bank's headquarters in Tokyo. Hanzawa denies fault and promises to retrieve the 500 million yen loan. He did this because it's the only way for Hanzawa to survive as a banker.

Japan has a conviction rate of 99.9% for criminal cases that go to trial. A lawyer (Hiroki Hasegawa) is able to defeat those odds and obtain an acquittal for his client, even though there's conclusive evidence that says otherwise. Sometimes, due to minor things, good and evil can switch sides and good people can become bad people.
