Restaurant owner Kenji Nagata has been stabbed to death. When the police begin an investigation, a bag of human bones is discovered in Nagata's car and Detective Kajikawa asks anthropologist Kumiko Misaki to perform an examination. She discovers that the deceased was a man in his mid-twenties and that he died more than 15 years ago. Meanwhile, suspicion for Nagata's murder falls on his apprentice chef Ryohei Miyamura due to the murder weapon being a kitchen knife. Afterwards, Miyamura breaks into Kumiko's lab, but manages to escape...

Mariko is a forensic scientist working at the Kyoto PD Crime Lab. Her credo is “science never lies” and she delves into the truth of the case with her colleagues with their specialized skills and knowledge in forensic medicine, physics, chemistry etc. Mariko’s steadfast belief in science makes her stand against conventional institutional ethics of the police department, diehard detectives averse to scientific investigation and sometimes even with her own colleagues, but she stays faithful to her belief in science and continues to pursue the truth.

The members of this elite investigative team are unique individuals with their own personal troubles, but what unites them is their strong sense of justice. They each channel all their energy and skill to solve the most difficult cases.

The #9 investigation team has been disbanded and members of the #9 investigation team have been scattered around. One year later, the Chief of the National Police Agency, Sojiro Kandagawa, orders the creation of a special investigation team to cover from the initial investigation until it is sent to the prosecutor's office. Sojiro Kandagawa appoints Sakutaro Munakata as the leader of the special investigation team. Former #9 investigation team members join the special investigation team.

With the progress made in forensic science, the number of cases of arrested criminals proven innocent because of new DNA tests have been increasing. The police always expect to swiftly solve cases. As crime scene detectives try to measure up to those expectations, they occasionally jump to wrong conclusions. Thus, the Tokyo Metropolitan Police's First Investigative Division set up the Evidence Verification Section and gave it the important task of validating cases that have been closed within a limited time in order to prevent wrongful convictions from happening as a result of out of control investigators at crime scenes. But its actual job is to correct typographical errors and omissions and stamp investigation reports with the words 'verification completed', and then send it over to public prosecutors. The members of the section headed by a veteran detective who worked his way up and has lost passion for his work, are a little idiosyncratic and somewhat difficult. It is merely a titular section meant to call the attention of the public to the fairness of the police. Deputy Inspector Shinkai Akira (Mizuki Arisa), a career elite who has been sidelined as a result of some incident, is assigned to be the new leader of the Evidence Verification Section. A sharp-minded female who gives the impression of an eccentric person, Akira breaks away from the bureaucratic work and genuinely starts to validate evidence, demonstrating her ability to take action and sense of justice in order to rally her disillusioned subordinates. Discovering new facts from small doubts in the reports, she overturns cases that should have been solved and finds the true criminals. -- Jdrama Weblog
