On the first day when Shen Xingyao, a graduate of the police academy, reported to work, he found that the new director's words and behavior were full of doubts. Based on the notes and intuition left by her father, she determined that this was a fake. In order to find out the truth, she teamed up with Chang Jiang Yan, the technical chief, to secretly investigate the background of the director. As clues emerged, a corrupt police group that had been entrenched for many years gradually surfaced, and the death of Shen Xingyao's father was also related to this. Veteran detective Zhao Tiezhu, secretary Chen Manni, deputy director Zhou Qiming and others have their own agendas. The true and false directors, family ties and grudges are intertwined. Shen Xingyao grew up in dangerous situations and vowed to bring the fake director to justice.
