A top notch seven-member team of doctors and nurses known as “Team Batista” are Tojo University Hospital’s pride and joy. The medical team performs a prominent heart surgery known as the Batista Operation which has a normal 60% success rate, but the team has consecutively pulled off twenty six successful surgeries. However, the streak is broken after a string of three procedures end in their patients' deaths. Consequently, an internal investigation is launched with hospital therapist Kohei Taguchi in charge of uncovering the truth behind the incidents. When Taguchi is unable to find any definitive information, the deaths are labeled as unexplainable accidents. The evaluation is subsequently dismissed by Keisuke Shiratori, an investigator with the Ministry of Health, Labour and Welfare, who re-launches the investigation on the basis that the deaths were actually murders.
