They struggle in their respective careers, friendships, love and power, and witness the conflict between conscience and interests when handling cases. Under the guidance of senior lawyers such as Xing Xu, the three were gradually drawn into the undercurrent of the legal circle: commercial litigation, criminal investigations, family secrets and law firm shady affairs. As the multi-line case progresses, the protagonists face moral choices and tests of human nature, continue to reflect on themselves and grow, and seek redemption amidst complex interest competition and ethical boundaries. In the end, they either choose to protect their original intentions or complete self-reconciliation. The story ends with humor, tense rhythm and in-depth characterization, revealing the breakup and rebirth between human hearts and legal principles.
