Retrata la historia de dos amorosas familias: una en la opulencia y con la ausencia de una figura materna y la otra de escasos recursos y con el gran sueño de encontrar a la más pequeña de sus integrantes.

Paz, cocinera talentosa, dedica su vida a la búsqueda de su hija secuestrada al nacer. Se enamora de Esteban, un viudo con tres hijos. Juntos deberán superar la oposición de sus familias a su romance.

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.
