Top actress Lin Xingchen retired due to a tax scandal. In order to come back to star in a legal drama, she disguised herself as an intern and sneaked into Hingyuan Law Firm. She thought she just wanted to "experience life", but she was accidentally involved in a core case of the law firm and had an intersection with the cold-faced lawyer Gu Yan. Gu Yan was full of doubts about the clumsy performance of this "newcomer", but he discovered her tenacity and intelligence through cooperation again and again. As the two team up to expose the shady industry, Lin Xingchen's true identity is gradually exposed, and workplace rules and emotional balance face a double test. When the storm of public opinion strikes again, can they find their sincere direction between truth and lies?
