One day, the younger sister of high school student Nana (Sawajiri) mysteriously disappears after picking up a discarded train pass at a station. Meanwhile, Nana's classmate Kanae (idol Chinatsu Wakatsuki) becomes stalked by an unknown presence after she finds a bracelet inside a train compartment. As Nana and a former train driver (Shun Oguri, from "Azumi" and "The Neighbour Number Thirteen") delve deeper into the mystery surrounding this 'lost property,' they learn of a woman who died in an accident on the same train line...
