A beautiful valley dotted with wineries and vineyards serves as the backdrop for this tale of love, hate, passion and intrigue. Valeria San Roman (Gabriela Spanic) is strong, rebellious, and a constant thorn in the side of her father, Don Chema (Hector Suarez), an ambitious man who acquired his wealth through treachery. Soon after leaving her fortune-hunting Fiance at the altar, she meets Francisco Contreras (Saul Lisazo), recent heir to his bankrupt father's winery. They decide to form a business partnership, which would not only save the Contreras family business, but also make Valeria independent of her unloving father. Initially, their strong personalities clash, but as they get to know and respect each other, a love develops between them that must withstand the forces that are trying to tear them apart. Among them are Don Chema and Francisco's young stepmother, Marcia (Catherine Siachoque), who become both lovers and allies as they conspire to take control of the Contreras ranch; also Roberto (Arap Bethke), Francisco's troubled son, and Belinda (Geraldine Bazan), Valeria's spoiled, capricious daughter, who believes she is her sister.
