In the case of a police officer accepting bribes, the senior officials of the Hokkaido Police Department are suspected of embezzling the investigation fee. In order to obtain evidence more thoroughly, the government set up the "Hundred Articles Committee" to directly summon witnesses from the police station. At the same time, a female police officer named Mizumura Asami (Otoguro Eri) was killed. The police officer Tsukui Taku (Miyasako Hiroyuki), who had a relationship with her and will testify at the Hundred Articles Committee again, is a major suspect. The senior officials issued a shooting order in an unusual manner, and Tsukui was in danger. At the same time, Koichi Saeki (played by Nanto Omori), who was eliminated from the Mizumura case, and his partners Yuri Kojima (played by Yasuko Matsuyuki), Masaki Shingu (played by Shugo Oshinari) and others felt that something was wrong. They gathered at the Black Bird Bar, a forbidden place for police officers, and decided to thoroughly find out the truth and send Tsukui to the committee safely... This film is adapted from the police novel "Utau Police Officer" by Joe Sasaki, and was shot by Haruki Kadokawa, the owner of Kadokawa Bookstore.
