Kohei Kuryu is an unconventional prosecutor at the Josai branch of the Tokyo District Public Prosecutors Office. One day Kuryu is asked to take on a case which his colleague, Shibayama, prosecuted. The case looks simple with a confession by the accused, but the accused changes his plea at the first hearing and now claims his innocence. Kuryu is faced with Kazuomi Gamo, an attorney who prides himself with the highest number of winning acquittals for criminal cases in Japan.
