Undersea Super Train: Marine Express

Synopsis

In 2002, the Marine Express—the world's first submarine railway linking America and Japan—is set to embark on its inaugural journey. Fearing that the trial run could be exploited for malicious purposes, the chief engineer hires private detective Ban Shunsaku to investigate. When Shunsaku arrives at the engineer's home, he finds the man murdered and catches only a fleeting glimpse of the assailant. Boarding the Marine Express, Shunsaku begins his quest to solve the crime. But he quickly discovers that the mystery runs far deeper than he imagined, as the train harbors secrets beyond anything he anticipated.
