Pedro, an inexperienced conman, decides to rob a bank. When he tries to escape, the branch is surrounded by police. His hostage turns out to be Pablo, the husband of the daughter of the bank's owner. After Pedro and Pablo leave the crime scene, Pedro demands ransom. But the money never arrives, since Pablo's father-in-law decides not to pay and, to make matters worse, instead sends an assassin to kill off Pedro.
The first part of the story begins when Juan's little daughter (Ethan Wayne), María Bonangelo (Grecia Colmenares), is adopted by the wealthy family of Encarnación and Manuel Olazábal, after the death of their biological mother, Amalia (Amanda Sandrelli ). María receives the last name of her new family, as well as two adoptive relatives: her sister Victoria (Viviana Saccone) and her aunt Asunción (Luisa Kuliok). The girls Victoria and María grow up as true sisters in a family ranch: "La Esperanza", until they arrive in the city of Santa María with their parents at approximately 20 years of age.
