Female lawyer Xu Jie, who was frustrated in her relationship and work in the original big city, was invited by the company's partner Li to go there and become an intern lawyer in the company. Xu Jie's specific goal is to uncover the corruption case of Chen Wenguang, another partner of the law firm, for Li. At the same time, she must start from scratch with a completely new upgrade.
Xu Jie was assigned to a less lucrative legal aid center and became friends with Chen Ran, who happened to be Chen Wenguang's daughter. Since his father was imprisoned, Chen Ran has been investigating secretly. After Xu Jie arrived at the company, the two lawyers with different concepts gradually became familiar with each other. With the successful resolution of a number of authorized cases, the two got to know each other and trust each other.
As the research gradually deepened, Chen Ran discovered that this rare work friendship seemed to have turned into a scam for the real reason of Xu's company. However, the constant incidents in the law firm tightly tied the fate of the two people together. After the two atone for each other's sins, they jointly explore the objective facts and finally learn the truth about the corruption case.
