Security guard Lin Hao is drawn into the sinister mystery of Splendid Garden. A nonexistent Room 1304, a mud monster with bloody handprints, parasites nesting in golden chains... Struggling between a reflection in the mirror and a bronze box, he discovers that the night watchmen are guarding not a door, but a three-hundred-year-old blood pact in the gap between the worlds of the living and the dead. When memories become keys and forgetting turns into a monster, he must piece together the truth written in souls before he is dragged to the Other Shore.
