In the heart of Rubí (
Bárbara Mori) reigns a constant struggle between every woman's desire to find true love and a desperate obsession with money. Although fate has denied her a good economic situation, it has instead favored her with extraordinary physical beauty and Rubí is determined to use it to marry a rich man who will give her the life of luxury she aspires to. Rubí studies at a private university thanks to a half scholarship and the support of her sister, Cristina (
Paty Díaz), who works hard to help their mother support the household. At the university, Rubí befriends Maribel (
Jacqueline Bracamontes), a millionaire yet sweet and simple girl, who was left disabled in one leg by an accident. Maribel thinks that, more than a friend, she has found a sister in Rubí and she cares for her sincerely, without knowing that Rubí's affection is poisoned by envy. When the beautiful young woman visits her friend's mansion, she becomes convinced that this is the kind of life she deserves and she will do whatever it takes to get it. Maribel, a shy young woman because of her physical defect, spends hours on her computer chatting on the Internet with a young man named Héctor (
Sebastián Rulli) and soon after they become a couple without ever having met. When they finally meet in person, Héctor overcomes Maribel's disability and asks her to marry him. Maribel accepts, happy and in love. Héctor introduces Rubí to his best friend, a young orthopedic doctor named Alejandro (
Eduardo Santamarina), and a deep love is born between them as well. When Maribel finds out, she feels that her happiness is complete. Rubí is also happy, because in addition to being in love with Alejandro, she thinks that life will finally do her justice when she marries a handsome and rich doctor who furthermore adores her. That is why she is so disappointed when she finds out that Alejandro's family is not wealthy. Rubí has to choose between marrying the man she loves and her desperate desire to be rich and, even though she knows that another love like this may never come into her life, she breaks off her relationship. Heartbroken, Alejandro walks away from her forever and devotes himself body and soul to his profession. Now, Rubí is more determined than ever to marry a millionaire and, to achieve this, she is willing to commit the vilest of betrayals by stealing Héctor's love from Maribel. However, even though her dream of luxury and wealth comes true when she marries Héctor, Rubí will finally have to learn a painful lesson: that vanity, pride and greed are terrible sins and divine justice is implacable. ==Cast==
