Shen Zhiwei, a three-time Best Actress winner, is publicly accused of "stealing a script" at an awards ceremony. Her former best friend, Song Qinghuan, tearfully claims she plagiarized, and the whole internet erupts. Unable to clear her name, Shen Zhiwei is forced to sign a nondisclosure agreement to pay for her seriously ill mother's treatment, then quietly quits show business. Three years later, under the alias "Lin Xiaoman," she works as an extra at a film studio while saving money and secretly gathering evidence. Then she discovers that the script for Song Qinghuan's new movie is actually the work of hers that was "stolen" all those years ago, and its producer is Lu Zeyan, the only person who believed her back then. Shen Zhiwei decides she won't stay silent any longer. Using her identity as an extra, she sneaks onto the set and reenacts a "key scene" from the old script right under Song Qinghuan's nose, hoping Lu Zeyan will recognize her writing. But Song Qinghuan is prepared. She pays off paparazzo Zhao Yiming to expose Shen Zhiwei's "dark past" and threatens director Chen Mo into giving false testimony. Shen Zhiwei is driven to the brink, but then she unexpectedly discovers that a video Zhao Yiming secretly filmed years ago contains conclusive proof of Song Qinghuan's plagiarism. She sets a trap for Song Qinghuan, making her expose herself on a livestream and unmasking her in public. But just as the truth comes out, Shen Zhiwei receives an anonymous letter that reads: "You think you've won? Who paid for your mother's surgery back then?" She suddenly realizes that this scheme is about far more than plagiarism.
