Regina's daughter, Yelena, is diagnosed with leukemia. Umbilical cord blood is their best hope. However, when Regina seeks out Jacob, who she has a fake divorce from, hoping to have a second child with him, she discovers he has been having an affair with Tessa, a secretary at the Hill Group, and is using their sham divorce as a pretext to seize her house. To obtain the cord blood to save Yelena, Regina endures humiliation from Tessa and Jacob, even disfiguring herself. Meanwhile, John, the president of the Hill Group, unexpectedly discovers that Regina is his long-lost daughter and Yelena is his granddaughter. John devotes all his resources to finding a bone marrow match for Yelena. However, Tessa, the only match, demands custody of Yelena in exchange. Just as Regina is about to sign away Yelena, John brings back a new match and successfully saves her. Ultimately, Jacob and Tessa's evil deeds are exposed, and they lose everything. Regina reunites with John and finds a new life.
