Synopsis

Although Eugenia Montiel was a minor when she committed a crime, she sits in prison for five years awaiting her judgment. She knows that the one responsible for her long imprisonment was the lawyer, Diego Mendoza; she hates him and swears to take revenge on him for this injustice. Silvana, a violent predator, hits her in the head with a fire extinguisher, which temporarily blinds her. A strange woman called Endrina visits Diego and asks him to repair his injustice. Taking advantage of Eugenia's blindness, Diego pretends to be a nurse, makes friends with her, and falls in love with her although he's already married to Pilar Luján with whom he has daughter María de los Ángeles. Before knowing the face of Eugenia, he marches, leaving her the truth in a letter. Eugenia gets free and goes to live with Endrina and her sister Cándida, who adopt her. Cándida knows the secret about Eugenia's origin, but she dies without telling her. Eugenia has only one clue: the name "Constitución Méndez"; with this she goes to Caracas to look for the cruel and powerful Constitución who is her real mother, something that both of them ignore.
