Wang Xiulan, a live-in nanny, donates her rare panda blood to save the critically ill young master of the Huo family, only to have the Huos claim her reward, frame her with a fine, and throw her out. Three years later, the Huo family offers seven million yuan for her blood. By then, Wang Xiulan has founded a domestic services company and is pregnant. She firmly refuses and lays down three conditions. Joining forces with numerous other victims, she endures evidence being destroyed, her lawyer turning against her, and losing the first trial. At last, she exposes the dark secrets of the Huo Foundation in court and brings the villains to justice. She also safely gives birth to a daughter and begins a new life.
