64: Part I

1989 is the 64th year of the Shōwa era in the Japanese calendar, thus the unsolved girl kidnapping-murder case is called "64(rokuyon)", as it originated in this year in the Criminal Investigation Department in the Prefectural Police Department. Unsolved for 14 years, it becomes the police’s greatest embarrassment, and it is approaching the statute of limitations. In 2002, Yoshinobu Mikami, an ex-detective who was assigned as the investigator of the "Rokuyon" case 14 years ago, is moved to Public Relations Officer in the Police Affairs Department against his will. As a newly assigned Public Relations Officer, he struggles with reporters, as a new case has occurred, which mirrors the "Rokuyon" case exactly.
