Kuryu Kohei 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 Gamo Kazuomi, an attorney who prides himself with the highest number of winning acquittals for criminal cases in Japan. While Kuryu is puzzled by the appearance of such a high profile attorney for a relatively minor case without publicity, Gamo steadily drives Kuryu into a corner with his unperturbed and varied tactics. Meanwhile, Tokyo District Public Prosecutor's Office is conducting the special investigation on the a bribery case of Hanaoka Renzaburo, a major Diet member. Unbeknownst to Kuryu, it turns out that the adjudication of the case holds the key to a bribery case of Hanaoka Renzaburo. Kuryu and Hanaoka had an encounter in the past, but Kuryu concentrates on bringing out the truth of his case and with his legal aide Amamiya.
