Qin Ming (Zhang Yao), who just entered the workplace, was accidentally involved in a homicide case while investigating the mystery of his mother's murder. He met An Ran (Tang Min), Lin Tao (Peng Chuyue), Huan Huan (Ma Xinmo) and other forensic doctors and police officers. Behind each case in the play is a social topic. Each case is independent but inextricably linked to a huge conspiracy. The series is adapted from the first work in the "Forensic Qin Ming" series.
