Plot
Regina Villarreal is a young and beautiful woman who inherits a fortune from her deceased parents. Regina lives with her aunt, Berenice, whom she loves as if she were her own mother, her unbearable and envious cousin, Laura, and her inseparable nanny, Martina. Laura feels that she deserves everything her cousin Regina has, so she decides to make her suffer by seducing her fiancé, Mauricio, who is only after her money. On her wedding day, Regina is left at the altar by Mauricio, which shatters her heart and transforms from a sweet woman into a cold and authoritarian figure.
Regina moves to one of her properties, "Los Cascabeles", a ranch far away from the capital city. She becomes a resentful and indomitable woman, "La Dueña" ("Lady Owner"), as her employees call her. Furthermore, her reputation earns her the nickname "Víbora" ("Viper") among the locals. There she meets José María, owner of the neighboring ranch "Los Encinos". Both fall for each other, but Regina does not reveal her feelings for him for fear of getting hurt again in a relationship.
Around this time, Berenice, Laura, and Martina also move to "Los Cascabeles". Macario, the foreman of the ranch, is in love with Regina and he and Laura scheme to keep Regina and José María apart. Laura has also fallen in love with José María; because of this, Regina will once again become a target for her cousin, even though this time Regina will not let anyone steal her beloved's heart from her.
