The heroine Su Mo, a legal genius with photographic memory and super logical reasoning ability, determined to become a top lawyer due to family changes. However, during her internship at a top law firm, she was framed by her boyfriend and best friend, accused of leaking trade secrets and expelled. She went from being a proud girl to being a disgrace in the industry overnight. At the lowest point in her life, she did not get knocked down, but chose the most difficult path - taking on the hard cases that no one dared to touch.
From fighting for the rights of women who were victims of domestic violence, to clearing the grievances of young people who were falsely accused, to exposing the shocking scams of listed companies, Su Mo relied on her extreme use of the law and persistence in the truth to stage shocking reversals in court again and again, trampling on those who looked down on her in the past. Her achievements attracted the attention of Lu Jingshen, a legendary lawyer in the industry who has long since retired. After Lu Jingshen secretly observed and tested her, he became her most solid support and mentor. In the end, Su Mo personally sent his ex-boyfriend and betrayer who framed him to prison, and uncovered the man behind the tragedy that caused his family. He used a trial of the century to clear the name of himself and his family, and was crowned the well-deserved "Queen of Law".
