To confirm her suspicions about the new student, Masami enlists a friend's aid in gathering evidence. Uncovering the truth may offer relief, but the implications could be more ghastly than imagined. Amid their summer break, reserved Miko and extroverted Nanako yearn for excitement beyond horror movie binges. When they set their sights on an abandoned mansion rumored to be haunted, two additional comrades join them on their expedition. As misfortune after misfortune strikes, chance or a miracle may provide their sole means of emerging from the mansion with their lives, mental states, and grasp on reality intact.
