Six years ago, Iris spent a night with a masked man to escape her family's sale. She raised her daughter Ella alone. Ella accidentally enters the Blackwood family, and three brothers—Zane, Ethan, and Xavier—all appear to be the father due to identical DNA. Iris becomes a nanny, faces schemes from her stepsister, and falls for Zane. Genetic testing reveals Zane is Ella's real father. The stepsister's fraud is exposed, and Zane marries Iris.
