In 2002, a 24-year-old Japanese man named Naoki left for work, then boarded a ferry that evening and vanished. He is one of Japan's johatsu, the "evaporated people" who walk away from debt, failed marriages, workplace shame, or family pressure and simply cease to exist under their old names. The film follows the network that makes this possible: night-moving companies that pack up an entire apartment in silence and drive clients across the country under cover of darkness, and the shanty districts and cheap rooming houses where the vanished resurface under new identities. Interviews with people who disappeared, and with the families left behind to wonder whether a relative is dead or just gone, lay out how thin the line is between the two once someone stops answering the phone. The film treats disappearance as a shadow institution particular to Japan, built on shame culture and a legal system slow to intervene, rather than as a series of individual tragedies.
