Rosaura Rios is a beautiful and kind young woman who lost her mother and who lives with her drunkard father. She has no choice but to work day and night to be able to sustain her family who lives in a small house next to the fabulous ranch of the wealthy Arismendi family. Luis Mario Arismendi is an educated and handsome young man, heir to the family fortune, who loses his wife in a very strange accident at sea, and she is never recovered. This event keeps him in a sentimental limbo for quite some time. Luis Mario decides to return from New York to take over the family business - the ranch -, which is not in good financial standing. As he returns, the small plane in which he travels suffers an accident very close by to the ranch. Rosaura, who is in the area, reaches him and rescues him. Luis Mario instinctively kisses Rosaura who reacts by scratching him on the face, thus getting the name of "Wild Cat". Destiny unites Rosaura and Luis Mario in many occasions, even resulting in their marriage. Eduarda and Eva - Luis Mario's sisters - are determined to see their brother married to a rich girl that will guarantee that they will not be financially ruined; but Luis Mario, in order to go against his wicked sisters, marries Rosaura, who is deeply in love him although he doesn't share the same feelings. Eduarda and Eva Arismendi make Rosaura and Luis Mario's life miserable and finally they manage to break their marriage. Now Rosaura alone, penniless and sad begins a new life. But her luck is about to change when she finds out that she is the only descendant of Mrs. Cruz Olivares de Reyes a powerful and wealthy old lady who wants to find her granddaughter before she passes away. Rosaura becomes a sophisticated lady that will use her fortune to ruin all of those who harmed her in the past, and surely enough she does, including Luis Mario. Rosaura, the "Wild Cat", one day realizes that her transformation has turned her into a bitter and heartless woman, and she comes to understand that the love she feels for Luis Mario is unbreakable, and that aside from all the things she did to the Arismendi family, she passionately loves him. Finally they will both be able to conquer the happiness that long time ago escaped them.
