[1] Esteban Olivares (Simón Pestana) is a man condemned to not be happy since he lost his memory and part of his life.

María de la Luz Centeno (Lilibeth Morillo) is the apple of her eyes, a recurring image of her lost past and which he ignores, is the mother of her son.

Esteban loved in his adolescence to María de la Luz, but an accident separated them leaving him amnestic.

Rosaura, her mother, who does not love her son's girlfriend for being a humble class, takes him to the United States where Esteban finishes his engineering studies.

Without being able to get news of Esteban, María de la Luz has a son Sebastián (Alberto Faría) whom she must raise alone.
