Kunihide Kiyomaru has a prior conviction for assaulting and killing a girl 8 years ago. The police could never apprehend the suspect in the prior killing.
Three months after the murder of his granddaughter, Ninagawa places a whole page ad in the 3 big Japanese newspapers. The ad states "Please kill this man Kunihide Kiyomaru and I will pay you 1,000,000,000 yen as a reward." Meanwhile, Kunihide Kiyomaru sees the ad and begins to fear for his life. Kunihide Kiyomaru then turns himself in at the Fukuoka Police Station. Five detectives from the security section (SP) of the Tokyo Metropolitan Police Department travel to Fukuoka to escort Kunihide Kiyomaru back to the Tokyo Metropolitan Police Department. The distance between Fukuoka and Tokyo is apprixmately 1,200 km. During their fateful trip, a significant portion of the Japanese population plot to kill Kunihide Kiyomaru. Many of those people, actually pursue Kunihide Kiyomaru while he goes back to Tokyo to get the 1 billion yen reward. The lonely fight of the five detectives to protect this man begins.
