Su Tiantian, Zhang Hang, and Lin Weiyu, three girls who have just stepped out of law school, plunge into the workplace with awe and longing for the law. Su Tiantian, a criminal law student who is cute but full of aura in court, Zhang Hang, an intellectual property law student who is cold on the outside but soft on the inside and prefers pink, and Lin Weiyu, a civil law expert who looks outgoing but is lonely and determined to tear up scumbags. The three of them were looked down upon and made things difficult for them in the internship law firm, but they united for warmth because of their common grievances and dreams.
By chance, they met Zhou Zhou, the "prodigal son" of the Yufeng Group - a rich second-generation man who was cynical on the surface, but actually disguised himself as a proficient in new media to avoid family disputes. They were first attracted by Su Tiantian's soft cuteness, and then were touched by Lin Weiyu's extroverted loneliness. Finally, they fell into the contrasting cuteness of the "iceberg beauty" Zhang Hang.
With Zhou Zhou's investment and help, the three girls broke free from their shackles and founded their own "Sanshu Law Firm". They use professionalism as their sword and justice as their shield: Su Tiantian defends clients with her super affinity and solid knowledge of criminal law, Zhang Hang handles difficult intellectual property cases one after another, and Lin Weiyu holds up the sky for countless women who have been let down.
On the road to entrepreneurship, they overcame obstacles and also gained their own love: Su Tiantian met the gentle veterinarian Gao Feiyu while traveling alone, Lin Weiyu met Li Jing in a bar who understood her loneliness, and Zhang Hang and Zhou Zhou worked together to break class prejudice and become each other's armor. In the end, the three girls transformed from newcomers in the workplace to legal elites, using law and warmth to write a counterattack legend about dreams, friendship and love.
