The story revolves around four beautiful 21-year-old girls who come from different social strata. The first of them, Laura, is a middle-class girl, serious, sensitive and studious, who can study computer science at a private university because she won a scholarship. There he meets Jimena de la O, daughter of a millionaire businessman. At first, there will be a lot of friction between the two, but little by little a strong bond of friendship will form between them. Jimena is the typical rich, dissipated and irresponsible girl, for whom promiscuity, alcohol and drugs have marked her life since her mother died.
