Tian Xi, a new lawyer at Mingyuan Law Firm, looks gentle and weak on the outside, but is as tough as iron on the inside. On her first day in the industry, she was spotted by senior partner Gu Mingyuan because her face was almost identical to that of the legal legend Bai Yueguang and Su Wan. Gu Mingyuan carefully cultivated her as a substitute, and his colleagues were particularly tolerant of her because of her face. Tian Xi knew this, but was unwilling to be just a shadow. In an accident, she awakened the golden finger's "Eye of Zhaoying" - when she touches case files or physical evidence, she can summon and reflect the real scenes related to them. She began to use this ability to "pick up" key evidence in various cases and repeatedly solve difficult cases. Xu Zechen, another senior in the law firm, appears to be highly respected, but secretly bribes witnesses, fabricates evidence, and has no bottom line. Tian Xi's sharp edge threatens his profit network, and Xu Zechen sets up a vicious plan to destroy her. However, Tian Xi is no longer a stand-in who can be manipulated by others. She joins forces with her colleagues who treat her sincerely, and uses wisdom and legal weapons to uncover Xu Zechen's crimes layer by layer. From a substitute to a group favorite, from a rookie to an ace, Tian Xi proved with her strength that Bai Yueguang can only be missed, but she can light the way for everyone.
