Naturally, Hitomi is incensed and galled by the idea. But Hitomi soon finds out that her mother knows her intimately, for she has been corresponding with her mother all her life, believing her to be a childhood friend who moved away. As a result, Kanako knows all of HItomi’s closest-kept secrets, her innermost thoughts, everything about her upcoming marriage and even… that she was recently diagnosed with a life-threatening brain tumor that may ruin plans for the wedding. Hitomi makes every effort to resist her mother’s unsolicited intrusion into her life, but blood is thicker than water. And so begins the 100-day battle between a mother and daughter. Can it end well?

Shinya Ryuzaki plays a pivotal role in the national police force as liaison between the police, Diet politicians, bureaucrats and the mass media. When he learns about the murder of a violent gang member through the newspapers instead of the usual direct reporting to him by media outlets, he is perplexed and seeks answers from an old friend and colleague on the police force, Shuntaro Itami, who is now Chief of Criminal Investigations. A series of ensuing crimes pointing to the same perpetrators begins to uncover links to a major unsolved scandal from the past, stirring up shadowy forces of corruption inside the police department. Ryuzaki forces himself to cast aside protocols of rank and status in favor of taking a thoroughly rational approach to solving the crime, embroiling his friend, Itami, in a lonely battle for justice.

Stemming from a need to speed up the capture of criminals using hard evidence, the Tokyo Metropolitan Police Department has just established a new forensic lab information and investigative authority section inside the Firs criminal Division, the top killer catchers on the force. The members of the forensic team are dubbed the “white coats.” Kazuki Kitamura stars in his first lead role for a TBS drama series as white coat investigator Satoshi Ichinose, who uses his advanced forensic skills and unique investigative methods to crack puzzling cases. He is joined by Shosuke Tanihara as “the human lie detector” Masayuki Honda, and Hiroyuki Miyasako ex-forensics ace, Toru Okunuki, to round out the cool white coat, forensic “geek” trio. While they all differ in personality and specialty, it is their cooperation and respect for each that solves crimes.
