Upon hearing at last the name that Delia had always refused to reveal, Ángela vows, with chilling determination, that she will not rest until she has found this woman and made her pay for ruining her mother's life.

Yolanda Rivas (Olivia Bucio), Emilia's right hand, takes pity on the seemingly sweet and shy young girl and persuades her boss to hire her.

Only one person mistrusts her and is not seduced by her apparent innocence: Mariano Bautista (Juan Soler), a young engineer who works in the silver mine.

Nevertheless, the oath she swore over her mother's grave binds her to her destiny and Ángela is now powerless to stop the tidal wave of destruction and suffering that she herself has unleashed.

Leading man Juan Soler eventually went to star with Yadhira three years later in the successful soap opera La otra.
