After programmer Chen Xun received a strange letter home from his mother, he was forced to return to his isolated hometown of Beiling Village. There is an abnormality everywhere in the village: every door and window has blood-red stickers crookedly on it, it is dead silent at night, and taboos are strict. When he unintentionally broke an unnamed rule, a strange suona sound followed the phantom in red. He must cooperate with Liu Jiu, a mysterious paper-making shop girl, to find loopholes in countless cruel folk rules and uncover the bloody contract between his family and the ancient "stele" in order to find a glimmer of hope in this village with strange rules.
