After noticing in the news there was a fire in an old canal town, Eguchi recalls visiting there a decade ago as a university student.

Hayato, a freelance photographer, heads to the vacation home of Nishimoto, a friend from his college days, with his friends and his beloved Emi, whom he meets again after a long time. It was supposed to be a fulfilling vacation. The next day, the group visits an abandoned house near the villa. A place he has been irresistibly drawn to for some time and has visited many times. Hayato clicks the shutter as if possessed by something. What was waiting for them there... Was it reality or illusion? Is it reality or an illusion? On a night when a pure white fog crawls across the land, a terrifying and sad nightmare begins.
