Lu Qingyuan, the daughter of a former minister of the Ministry of Justice, was executed because her father was wronged. She changed her name to Lin Yanqiu and lived in the border Yanxi County, hiding in the county government and working as a low-level scribe.
When a suicide case file revealed a flaw, the county magistrate Gu Huaizhi noticed her talent and promoted her to an assistant criminal agent.
Lin Yanqiu repeatedly solved mysterious cases by deducing from the files and gained a firm foothold in the county government. He also discovered that each case was vaguely connected to his father's unjust case back then. Gu Huaizhi has been secretly investigating old cases of the Lu family for many years. The two went from testing suspicion to trusting each other. After confirming their minds, they worked together to investigate the case, gradually tearing apart the chain of local corruption and pointing to the mastermind behind the scenes in the DPRK.
In the end, the two gathered evidence and joined forces with upright officials to vindicate the Lu family. Lu Qingyuan gave up his official career in Beijing and stayed in Yanxi to guard the judicial system, while guarding the world of fireworks with Gu Huaizhi.
Purpose: To tell the story of the growth process of Lu Qingyuan, the daughter of a criminal minister, who hides her name and uses her criminal name to find her way to the frontier county government, redressing her family and speaking out for the weak. Convey the belief of sticking to the bottom line and supporting justice, and show the resilience and strength of women in difficult situations.
