University student Sugishita Nozomi, Naruse Shinji, Ando Nozomi and Nishizaki Masato end up coming upon the scene of the murder of the Noguchi couple, because of a plan they had devised. Nishizaki is arrested at the scene and is given a 10-year prison term because of his voluntary confession. 10 years later, Takano Shigeru, a former police officer who has misgivings about the verdict of this case, starts to pursue the truth.
