A bank robbery occurred in the city, with several hostages taken, including Police Chief Mizuki Eiko (played by Manami Konishi). Yamada called his friend Asaru (played by Hayato Ichihara), who successfully cracked the back door lock of the bank, allowing riot police to enter. Although the robbers managed to escape, fortunately, both the bank and the hostages were safe. Shortly thereafter, one of the hostages, Mamiko (played by Aimi Noguchi), approached Asaru, claiming to suffer from intermittent amnesia, which prevented her from remembering the vault's password, hoping he could help. Enchanted by her beauty, Asaru agreed, not realizing he was getting himself into serious trouble. The vault Mamiko referred to belonged to Fuhara Kō (played by Ken Mitsuishi), a prominent figure in both the underworld and the police force. Mamiko's betrayal triggered a pursuit by Fuhara and caused a huge stir in the police community... This film is adapted from Naoki Serizawa's original work of the same name.
