The new prosecutor Keiichiro Okino (played by Kazuya Ninomiya), who has a strong sense of justice, admires his former mentor Takeshi Mogami (played by Takuya Kimura). After several years of experience, Okino finally got his wish and was transferred to the Criminal Police Department of the Tokyo District Public Prosecutors Office, becoming a capable general under Mogami. At the same time, Saho Tachibana (played by Yuriko Yoshitaka) also joined the Criminal Police Department and became Okino's affairs officer, but her real identity was undercover, and her purpose was to obtain hard evidence that the prosecutor used extraordinary and even illegal means to win the crime. Not long after, a murder case of a couple brought the suspect Shigeki Matsukura (played by Yoshimukai) to Okino. Matsukura was a suspect in a murder case of a teenage girl 23 years ago, but due to lack of evidence, he could not be convicted and the case eventually passed the statute of limitations. The resentful Mogami stubbornly wanted to bring Matsukura to justice, and for this he did not hesitate to instruct Okino to do his best to move in the preset direction. In the face of human nature, no one can maintain 100% justice. The film is based on the 2013 novel of the same name by Shizukui Shusuke.
