Eight years ago, in 1988, 17-year-old Hiroki and his bad friend Takashi were threatened by the head of a gang called Miyamoto and kidnapped and imprisoned 17-year-old high school girl Osawa Sachiko.
A group of gang members led by Miyamoto capture Sachiko Ozawa, a high school student, in Chiba Prefecture, and after assaulting her at a hotel, confine her at a house in E-Ward, eastern Tokyo, where they commit acts of rape and torture.
Her sister Miki frantically attempts to find her and takes the initiative, distributing flyers.
As fellow gang member Takashi Ikuno is the only murdered victim, ringleader Miyamoto avoids the death penalty.
