Su Li, a top student in psychology, signed a "deed of sale" with the underworld after a car accident. In order to become a formal judge, she bound the KPI system and returned to the human world to open a psychological consultation room. Her clients are special: they are ghosts haunted by obsessions who have not yet reached the end of their lives. Relying on the "hearing ear" that can listen to the voices of all things, she reversed the case of the boy who jumped from the building, helped the nagging grandma convey a message, and helped the down-and-out singer realize his dream... With the help of the lazy supervising judge and the keen and upright criminal police, she walked on the edge of yin and yang, using psychology to resolve unresolved cases and grievances. Until she discovered that behind the 99 KPIs, there was a huge grievance that could subvert the entire city.
