On a stormy night, beautiful Marina was apparently stillborn. The labor was assisted by Damiana, the town’s midwife, who also assisted a healthy boy’s delivery a few hours earlier. Sadly, that boy’s mother died at giving birth. Don Luis, Marina’s father, has been obsessed with having a boy ever since he married Prudencia, so he is constantly threatening his wife with leaving her for a woman who can give him the heir that will immortalize the Ocaranza’s name if she doesn’t.
Unfortunately, after giving birth to the little girl, Prudencia won’t be able to get pregnant again, which encourages her nanny Angustias to convince Damiana of benefiting the orphan baby and his family by passing him off as a legitimate Ocaranza Arzuaga. this way, Alberto, Don Luis’ pride, is raised in a silver spoon and gets to travel abroad to study medicine.
Marina miraculously survives and grows happily around nature next to Damiana, who teaches her how to see the world differently for Marina was born blind. Marina’s charm, resulting from her joyful, fresh, and self-sufficient attitude, makes her win everyone’s heart. One day, Doctor Isauro enters Marina’s life and is mesmerized by both, her inner and external beauty, so he takes her under his protection and educates her.
Damiana’s house is accidentally set on fire with Marina inside. Just like that, Isauro breaks into the shack to save her and his face is disfigured by the fire. From then on, kind, sweet, and handsome Doctor Isauro turns into a selfish and resentful man. A loner who only allows and enjoys Marina’s presence.
