Strange things have been happening in Fuyun City. Without warning, people stop moving and face the same direction, wearing stiff smiles as if something has frozen them in place. Lin Yue, a high school senior, is the first to notice that something is wrong: footprints disappearing from the sports field, figures standing against the hallway walls, pale gray shadows crawling in through the gap beneath the door... More and more people stand motionless, until the September fog rolls in and swallows the entire school. His classmates twist into inhuman shapes right before his eyes, then... stand up smiling. Lin Yue makes it out by sheer luck, only to discover that his parents have already disappeared. An old notebook reveals a horrifying truth.
