Strange things are nothing new in the dead of night in Xishui Town, much like how Yu Han, a newly graduated village doctor, has never believed in ghosts or gods.
That is, until a woman in white showed up smelling strongly of river water, pressed a blood-red jade into his hand, and asked if he'd seen a man wearing a floral shirt.
He thought it was just some lovers' elopement gone wrong. But as he was closing the door, he saw a severed hand wedged in the doorframe, pale and slender, stained with dark red blood, much like the woman's hand.
Even stranger, the man in the floral shirt appeared out of nowhere, and the severed hand vanished just as suddenly. The blood jade in his palm began to grow hot, as if he were holding a living heart.
When the town's elders spoke of the water ghost said to haunt Black Dragon Pool, and villagers began crying out that their hands hurt as they muttered about the woman in white, Yu Han finally realized the suona music he'd heard that night wasn't a hallucination. The missing people and the severed hand weren't a dream, and the blood jade in his hand had already dragged him into a wait that spanned life and death.
Strange events pile up in Xishui Town, and the blood jade has appeared. Village doctor Yu Han is caught up in a deadly mystery.
