Watch on SFlix. Director Wang Jian visits a desolate village at night and learns from an old woman, who has been guarding the ancient village for decades, about a massacre caused by greed: After the villain Hu Rencheng struck a gold vein, poisoned his benefactors, sexually assaulted a young girl, and drowned the witnesses in the lake, he was eliminated by his senior, Uncle De, at the cost of Uncle De's life. Uncle De blocked the spring with his body, and the lake water became clear again. The old woman telling the story is Uncle De's young apprentice who swore to guard this place back then—what goes around comes around, and the guardianship never ceases.
