Su Wanqing is pressured by her boss, Gu Mingchuan, to sign a resignation form. She counters by presenting the original non-compete agreement and demands three years of compensation, threatening to take the company to arbitration if they refuse. Gu Mingchuan thinks he can get rid of her easily, unaware that the agreement conceals a scheme by the investor, Hengyuan Investment. Su Wanqing pits her wits against legal director Zhao Haifeng, receives secret help from assistant Lin Xiaoting, and unexpectedly finds an old journal belonging to Lao Zhou, the janitor. Little by little, she uncovers the truth about Gu Mingchuan being forced to compromise with the investors. Chen Liqun, the investors' representative, is also reminded of his original ideals by Su Wanqing's determination, and switches sides at the last moment. What began as a battle over resignation becomes a fight against the rules of the game imposed by capital.
