Financial analyst Lin Wan discovered something fishy in the company's accounts during a routine inspection and was accidentally involved in a cross-border money laundering case. In order to find out the truth, she transformed into the hacker "Rose" to investigate secretly, but in the process she discovered that the matter was closely related to the mysterious death of her father seven years ago. Justice lawyer Lu Chenzhou met Lin Wan because of a case. He was moved by her persistence and decided to use legal means to help her. Huo Hanchuan, the seemingly glamorous president of Hanchuan Group, is actually the leader of a criminal group. He and his minion Zhou Yan constantly put pressure on Lin Wan and obstructed her.

After experiencing identity exposure, trust crisis and life and death tests, they finally tore apart the disguise of the criminal group in court, letting the truth be revealed to the world, and completing the consolation and self-salvation for their father.
