DIE was forced to disband, and the original team members returned to their original jobs. This group of people did not change their previous eccentric style, which made the leaders very headache. In order to avoid these difficult subordinates, Zilang (played by Roger Kwok)'s immediate boss Luo Youheng (played by Guo Feng) took the initiative to propose to reorganize DIE. However, since the original head of DIE, Fei SIR, had retired, Luo Youheng was forced to take over. Jingjing (played by Sonija Kwok) also quickly returned to DIE after her maternity leave. Zilang and Jingjing had nowhere to place their child, so they had to take him to the police station, and a series of exciting cases were staged one after another. On the other hand, Zhengyi (played by Guo Zhenghong) and Ziqing (played by Zeng Huaqian) were in a relationship crisis. Everyone also gradually discovered that Zilang's child had inherited his father's supernatural powers, and Jingjing also solved cases repeatedly. Who knew that he would get into trouble again? Can Zilang, Jingjing and his family of three escape successfully? Is Zhengyi and Ziqing really destined to be together?
