Ana Paula lives in Chiapas where she is studying nursing; her devotion for sick people came up while she took care of her ill mother throughout her long agony. When she was about to graduate, she met Bruno, Rogelio Montero’s lawyer. Bruno offered her a job nursing his boss who became paralytic and got stuck in a wheel chair after having an accident. The pay is good so she takes the job in order to financially support her aunt Rosaura, who has been like a mother to her and her brother Miguel ever since they were kids. Ana Paula arrives in "La Hacienda Del Fuerte” to look after Rogelio and she is surprised to learn that he is a bitter, resentful man mostly because Vanessa, his shallow fiancée, left him after the accident. In the hacienda also lives Cynthia, Rogelio’s sister, who is in fact kept there by her brother since he forced her to stay and take care of him in exchange for keeping the lifestyle she is used to have. To avoid boredom, she began an affair with Efraín, the Hacienda’s foreman; he actually falls in love with her, but she is only using him for fun. With them also lives their nanny, María, who has always acted as a loving mother to Rogelio and Cynthia, and who is not able to ever leave them. Rogelio’s arrogance and bad mood make it very difficult for Ana Paula to work with him, so one day she decides to quit. She has an accident in the river and she is rescued by Gustavo Durán, a handsome and good hearted engineer. They fall in love but their plans are frustrated when Gustavo has an accident with his father and Ana Paula believes he is dead. Rogelio has also fallen in love with Ana Paula, so he sends Bruno to look for her and ask her to come back to the hacienda. At first she refuses, but afterwards, when Miguel is blamed for crashing a truck, it could send him to jail for life, Rogelio offers to help him if Ana Paula agrees to marry him. She accepts the sacrifice just to help her brother, and so she marries Rogelio. Gustavo co
