Paz Roble, a kind, hard-working and honest woman from whom her husband, Fermín, takes her newborn daughter. Fermín has a large debt with some lenders and to pay it he decides to sell his daughter to Mauro Nicoliti. This plagiarism is orchestrated by Geneva, Mauro's adoptive sister. She lost her first-born daughter in childbirth and does everything to replace her dead daughter and keep her husband's fortune. On the other hand, Esteban Villa de Cortés loses his wife and becomes a widower with his three children. Elvira Moncada, Esteban's mother-in-law, holds him responsible for the death of her daughter. After a series of unexpected events, Esteban and Paz meet in the neighborhood where she lives with her family. The chemistry and great understanding that exists between them makes it inevitable that they will fall in love.
Fermín meets Ginebra again and she confesses her intention to take 'Monito'; he refuses because he is his daughter's best friend and could get him into trouble with Paz. Humberto becomes present in Esteban's life and he feels envy when he sees the relationship he has with Porfirio. After inviting him to stay for a few days, Humberto proposes that he prove that he can manage the land and thus he will disappear forever. Ginebra plans her revenge against Elvira with Mauro. Paz begins to suspect Nicoliti's intentions and her fear takes over when he asks to meet her. Ginebra asks for help to find her daughter and through hints causes Paz to fear being accused of taking her away.
