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.
Esteban manages to communicate with Paz to inform her that he found his daughter María and it will be at his wedding with Ginebra where he can meet her again. Paz prevents Esteban from marrying a woman he does not love and in front of all her guests, he challenges him to tell her that he has no feelings for her. Elvira, knowing that Paz is about to reunite with her daughter, wishes her that all the love she has is only for María and assures her that miracles exist. Mauro and Ginebra put together a whole plan so that Paz can meet her daughter, but Humberto asks her to be cautious, since they are not sure that she is María.
