Rubí Pérez (Bárbara Mori) is a very beautiful but poor woman who is only interested in money. She studies at an exclusive university thanks to the financial support from Cristina (Paty Diaz), her hard-working older sister. Rubí hopes to become rich by befriending rich people. She is best friends with Maribel de la Fuente (Jacqueline Bracamontes), a kind and wealthy young woman. Maribel has a paralyzed leg, which prevents her from having a normal social life. Rubí is actually jealous of Maribel's social status while pitying her disability.
