Based on a novel by Jiro Asada, Metro Ni Notte's reflection on the past follows a pattern familiar from other adaptations of the author's work. Here Shinji has long had a difficult relationship with his father, to the extent that he has even legally separated himself from the family, changing his name from Konuma to his mother's maiden name of Hasebe. Although he works in the same business line as his father, as a salesman for a small clothing firm, his father's approach to business is much more ruthless and on a grander scale, but the name Sakichi Konuma is famously associated with big business scandals and corruption. Although he doesn't see it, Shinji is perhaps rather more like his father than he would like to think, displaying a certain amount of cold-heartedness and having disowned to some extent his own family. This fact is pointed out to him, not a little ironically, by his mistress, Michiko.One day however, a meeting with an old school teacher in the Tokyo underground is a catalyst that propels Shinji quite literally back into the past. Believing that he has seen his brother Shoichi, who died in 1964, Shinji follows him out of the underground station to find himself back in time on the fateful day that his brother died in October 1964. Can his intervention change the past? Or, as subsequent trips indicate, does he need to go back further and confront the real root of the problem - his father?
