Andrea (Susana González) is a young and beautiful woman, with a strong will to live even though her life expectancy is short; she suffers from a potentially fatal heart condition.
She works as a seamstress at a clothing factory. One day she is assigned to make a bridal veil for Raquela Villaseñor del Moral (Cynthia Klitbo), the factory owner’s daughter, who is engaged to José Manuel del Álamo Sánchez (Eduardo Santamarina), a famous cyclist.
Fate will make this veil, created with much love and dedication, to eventually belong to Andrea. José Manuel realizes too late that whom he truly loves is Ángeles (Marlene Favela), Raquela’s sister. Ángeles loves him too, but she is very aware that their love is impossible.
Ángeles suffers a fatal accident at the same time that Andrea has a heart attack. Ángeles is an organ donor, and Andrea's life is saved when she becomes the recipient of Ángeles' heart. After losing his true love, José Manuel’s personality changes drastically; he is no longer the happy and cheerful young man that he used to be.
Yet he gets another chance at love when he meets Andrea, who has always admired him as an internationally renowned champion athlete. Soon they fall in love. He does not know that she received Ángeles' heart.
Raquela comes to suspect and fear that the ghost of her sister still lives on in Andrea’s new heart and that it has returned to steal José Manuel from her again. Meanwhile, Azael Villaseñor (Héctor Suárez), Raquela's father, is pressuring José Manuel to fulfill his promise to marry her.
Andrea is unsure whether José Manuel loves her for who she is or for the heart that once belonged to Ángeles. Despite this and many other obstacles, they decide to get married. At the wedding ceremony, Ricarda (Blanca Guerra), José Manuel’s mother, full of hatred for Andrea, pulls out a gun, intending to kill her right at the altar.
She takes aim and shoots, but the bullet meant for Andrea hits José Manuel instead. He dies at the altar, in Andrea’s arms. A grieving Andrea, wanting to start anew, moves to Guadalajara joined by her loyal and trusted friend Vida (Niurka Marcos). Unbeknownst to Andrea, Raquela is also living there with an aunt.
One day, Andrea has a mishap on the street, and that is when she meets Jorge Robleto (also played by Eduardo Santamarina). She is shocked by his uncanny resemblance to José Manuel. Although Andrea no longer believes in love, she begins to fall for Jorge.
She is unaware that Raquela has met him already and plans to win his love at all costs. This will now bring even more suffering to Andrea. Still, fate will intervene to ensure that the veil is worn by its deserving owner.
