It is based on the 2015 Portuguese telenovela Coração d'Ouro, created by Pedro Lopes. The series stars Mayrín Villanueva, Gabriel Soto and Gala Montes. It aired on Las Estrellas from 2 March 2026 to 19 June 2026.
Plot Luz lives with her daughter Catalina in a humble housing unit where she also has a taco stand. With what she earns there, she supports herself and her daughter. Catalina pretends to be a millionaire at school and doesn't mind taking every last penny from her mother to buy clothes to look expensive. One day, Luz receives a business proposal from a regular customer, Alberto, who claims to be a businessman. Luz discovers that Alberto is nothing more than Antonio's driver, whom she hasn't seen in over 20 years. At that time, Luz was fired from the Arango-Nova estate, accused of stealing a necklace from Antonio's wife. Antonio reveals to Luz that years ago his wife confessed that she fired her for having an affair with her son Eugenio, and that to keep it a secret, she made up the story about the necklace. Antonio wants to correct the mistakes of the past, so he offers Luz a job and to live at the estate again. Luz rejects him, revealing that she is keeping a secret about what really happened to get her fired.
Antonio meets Catalina, learns that she is Luz's daughter, and decides to tempt her with the idea of living on the estate so that she can help him convince her mother. Fascinated by the change of lifestyle that life on the Arango-Nova estate could offer her, Catalina tries to convince her mother, but faced with her refusal, she decides to start a fire in their apartment. Homeless, having lost everything, and faced with Antonio's promise that Eugenio will not return to Mexico, as he is now living in Spain, Luz agrees to return to the estate.
Teresa, Eugenio's sister, informs him that Luz has returned to the estate and he decides to return to Mexico. Catalina discovers that Antonio has included her mother in his will. However, faced with Teresa and Eugenio's attacks and their insistence that Antonio remove Luz from his life, she misinterprets Antonio's actions and believes that he is going to remove Luz from the will. In a fit of desperation, Catalina murders Antonio by suffocating him with his pillow so that everyone will believe that his illness killed him. As she leaves the room, she comes across Miguel Ángel, Antonio's blind son, who does not recognize her, but understands that his father did not die of natural causes. The reading of the will reveals that Antonio left a large sum of money and an important position in his company to Luz, which places her under suspicion.
Catalina confesses to Luz that she killed Antonio, assuring her that she did it at his request, as he wanted to end his suffering from his illness. Luz is not willing to let her daughter be accused and sacrifices herself by taking responsibility for the murder. However, after spending time in prison, it is discovered that Luz was elsewhere at the time of the crime and she is released. No one understands why she took the blame or who she is trying to protect. Upon leaving prison, Luz is a changed woman, determined to assert her rights and face the family and business war declared on her by Eugenio, Teresa, and all their accomplices.
