[5] 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.

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.

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.

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.
