Lin Xiao, a down-on-his-luck Taoist, just wants to coast through life. But his master kicks him out of the sect, forcing him to become the “free labor” of his unscrupulous martial uncle. He thinks he’ll only have to deal with ordinary paranormal cases, unaware that he has stepped into a world on the brink of collapse. As he is forced to grow, he discovers that the world is far more insane than he ever imagined. When the line between reality and the uncanny blurs completely, he must choose: succumb to the power, or find a way forward amid the struggle to hold on to his humanity.
