"99.9" is the percentage of criminal cases which are convicted in courts in Japan. It shows the high credibility of the Japanese judicial system, but on the other hand, it also suggests there is a big pitfall. While the prosecution is almost always the only testimony which is accepted in court, there might be a dismissed truth in the other 0.1% A lawyer -- Miyama (Matsumoto Jun) often takes on cases which do not bring him a lot of money. One day he is headhunted by a director of Madarame Law Firm (Kishibe Ittoku), and is assigned to the Criminal Case Department. Miyama teams up with Sada (Kagawa Teruyuki) and Ayano (Eikura Nana) to work on a murder case but his unconventional approach causes a conflict between them.
"Hiroto Miyama is a poor lawyer who takes on criminal cases, but unable to make money. He pursues the truth for the 0.1% out of Japan's 99.9% conviction rate. One day, Hiroto is scouted by Haruhiko Madarame. Haruhiko Madarame is the head of Madarame Law Firm which is one of the biggest law firms among the 4 big law firms. Hiroto Miyama begins to work with Atsuhiro Sada. Atsuhiro Sada is a lawyer specializing in civil cases and makes lots of money for the law firm. He doesn't have any interest in criminal cases which can not make money."--Amazon
