Asari Yusuke is a detective who works at a detective agency in downtown Tokyo. One day, a woman who knows his identity comes for a visit. She claims to know about the murder incident involving Yusuke’s parents and grandfather, which took place 30 years ago. Being a young child back then, he was adopted by his mother’s close relations. Meanwhile, even though the suspect had proclaimed his innocence at his court trial, his desire for a retrial had been declined three times, hence he is now a prisoner currently on death row. The woman believes that Yusuke is the only one who can work on the case, and reveal the real truth. (Source: Fuji TV)
