Takano Kazuya, a former surgeon turned lawyer who is gifted in deduction, gets scouted by the prestigious law firm, Shidanzaka. Its founder Saeki Makio was a charismatic lawyer but passed away all of a sudden. The man’s daughter Mei, who is also a lawyer, has brought Takano in to help her turnaround the law firm. There are four lawyers left in Shidanzaka’s Room 1 which is in charge of criminal matters – Mei, who is a rookie; Sugimura Teppei, a lawyer with an inferiority complex who was not in employment, education or training at one point; Kiryu Miyuki, a very proud lawyer who used to be a judge; and Umetsu Seijuro, a compassionate lawyer who was a former detective. The first case that Takano is assigned to handle involves a suspect called Hosaka Osamu, a part-time worker at a fishing boat shop. He is accused of letting an angler Kurahashi Ryuichiro, the CEO of a major F&B group, drown. It is a case that is ordinarily subject to “emergency evacuation” where an acquittal can be obtained. However, Takano suspects murder. He goes on to solve a string of difficult cases with perceptiveness and intelligence, and the cohesiveness of the team around him gradually grows stronger. Takano will end up having to defend a significant case that is connected to his own past.
