Mujer bonita Salomé Valentina (1975)

La Intrusa (International Title: The Outsider)^[2] is a Mexican telenovela produced by Ignacio Sada for Televisa in 2001. It is a remake of the Venezuela telenovela Valentina, produced in 1975. It stars Gabriela Spanic and Arturo Peniche

It was the second collaboration on-screen between Spanic, Andere, and Paleta, who three worked in La usurpadora (1998).

Rodrigo Junquera, who is close to death after an illness, decides to ask the nanny of his young child, Virginia Martínez, to marry him so she can look after his children when he's gone.

Virginia is a noble, young woman who is in love with Rodrigo's eldest son, Carlos Alberto. After his death it is discovered that Virginia is Rodrigo's wife, the heir of all his wealth. Carlos Alberto, along with his siblings, then accuse her of being an ambitious woman who married Rodrigo in secret.

Virginia's ordeal begins because she not only has to deal with the contempt of Carlos Alberto, who is still in love with her, but with the rudeness of Rodrigo's oldest children: Junior, Raquel, and Violeta. With the love of Aldo and Memo, the little ones, it makes coping with the friction within the mansion a little better.

Meanwhile, in another part of the country, a young woman named Vanessa is dedicated to deceiving millionaires in order to get their fortune, eager to get out of the miserable life she leads. She is the twin sister of Virginia, who has distanced herself so that their relationship is almost nil.

Beset by debt, Vanessa one day travels to Mexico where she meets Carlos Alberto, with whom she falls in love. However, despite her being a physical clone of Virginia, he despises her for her rudeness and impudence and just appearing like Virginia.

Virginia and Carlos Alberto marry, but after a series of faintings and loss of vision, Virginia discovers she has an inoperable brain cancer. At the same time, the medical findings confirm that she is pregnant. She finds that bringing the baby into the world can hasten the time of her fatal outcome. Virginia, disregarding the doctor's advice, decides to go ahead with the pregnancy. Blind and with the tumor extending inevitably, Virginia manages to give birth to a beautiful girl; but she dies afterwards.

The news of the death of her sister and the birth of her niece reaches Vanessa, who decides to go to Mexico to avenge all the slights Virginia suffered and to take care of her niece.
