Five years have passed since Kuryu Kohei's transfer from Tokyo to Ishigaki, and then to Sapporo. He ends up in a small town of Nijigaura in Yamaguchi Prefecture. There, he investigates a murder case involving a local enterprise, Kamoi Group, and the people related to it. Everyone in town thinks he's innocent except Kuryu, whose unorthodox investigation methods perplex not only the townspeople, but his colleagues as well.

After six years away, D.A. Kuryu Kohei (Kimura Takuya) returns to his former Josai branch of the Tokyo District Public Prosecutors Office, just in time for a brewing storm. Kohei's first case starts out simple enough. The suspect, a blonde-haired security guard, had already confessed to manslaughter, but he suddenly retracts his confession and takes things to court with big-shot defense attorney Gamo (Matsumoto Koshiro). It turns out that the security guard is a key alibi witness in a high-profile political corruption case, and the results of his case will directly affect the next. With the media, politicians, and a special investigative team breathing down his back, Kohei must handle the case with care (and flair) to find out the truth.

Prosecutor Kohei Kuryu takes charge of a case with a foreign embassy possessing the key to solve the case. Due to the extraterritoriality involving the case, the investigation has not gone anywhere. A crisis then ensues. Kohei Kuryu and his office attempt to extract the truth behind the wall of the Neustrian Embassy.
