Security guard Zhao Pingchuan sees ghosts floating in the community every night when he patrols, but he never panics - after all, he was a judge of the underworld in his previous life and is only temporarily retired. When the century-old ghost Lao Zhoutou planned revenge, the female college student Bai Ling'er was possessed by fragments of the Book of Life and Death, and the ghost captain Cui Jiuhu stared at him, Zhao Pingchuan patted the judge's pen on his waist and laughed wildly at the ghosts: "Who wants to jump in line and be reincarnated? I'll give you a quickie." A double drama between the human world and the underworld was quietly staged in the surveillance blind spot of Qingyun Community.
