Police academy student Lin Shen enters an old mansion deep in the mountains, the Listening Pines Lodge, while searching for his missing father, only to become entangled in a deadly seven-night blood-moon trap. Every time the old man with the rotting face beneath his bamboo hat finishes telling a story about one of the Seven Deadly Sins, a terrifying legend becomes a rule of death. The Grinning One, who must be met with silence, and the Seamstress Ghost, who feeds on jealousy, awaken one after another. Lin Shen awakens the Ghost-Seeking Eye and a supernatural tale System. Amid his teammates' suspicions and the pursuit of monstrous entities, he works to unravel the rules, only to discover that the mansion is an altar meant to awaken an ancient god, and that his father is the key sacrifice. As the blood moon rises and the wooden house transforms into a maze of flesh, he must lead his team in overturning the ritual amid Lovecraftian horror. But the truth behind the System is pushing him toward a new pact with death.
