With the love and unconditional support of his wife Lucía (Laura Flores), Ramón Mendoza (Sergio Goyri) has progressed in his work to achieve an excellent economic position. Their two children, Liliana (Florencia de Saracho) and Miguel Ángel (Franco Gala), have attended the best schools and never have endured the shortages that their parents suffered at the beginning of their marriage. However, Lucía is not happy; Ramón has become materialistic and cruel. He constantly humiliates her and has made it so that their children have lost respect for her. Liliana, spoiled and capricious, goes as far as to follow her boyfriend to Spain, where the boy gets her pregnant and abandons her. Hiding the secret of her maternity, Liliana leaves her daughter Natalia in the care of some nuns and returns to Mexico, where she must steal money from her father in order to care for the baby. Miguel Ángel, for his part, is a lazy and irresponsible boy who believes that he deserves everything. Lucía has become a shadow, an insecure and sad being that doesn't know where her dreams have gone. Her only happy moments are when, alone before her computer, she opens her heart to a twin soul who understands her, advises her, and with whom, little by little and in silence, she has been falling in love — that mysterious man whose face she can only imagine, whose voice she has never heard, and who signs his messages simply as "wind".
