As the Yangtze enters its dry season, a sandbar hidden for a thousand years emerges. Lin Che, a treasure hunter who braves the river's currents, finds a bloodstained grain-transport token in the water, setting off a doppelganger curse tied to a century-old vengeful spirit. Afraid of water, he suffers the backlash of his psychometric ability: the instant his fingertips touch a relic, he sees the truth of his father's grisly death, pushed into the river by a shadow. The ancient village did not sink by accident, his grandfather did not simply vanish, and even Su Wan, the folklore researcher at his side, is bound to a feud with the Lin family spanning three generations. As porpoises weep blood and statues open their eyes, the day the lotus tokens are assembled will become either a path to atone for the village's massacre or the moment he becomes the vengeful spirit's next substitute.
