Shortly after marrying Pepe Sancho, María receives the hardest blow of her life when she loses her daughter Rocío in a traffic accident, when she was only 16 years old. A blow from which María never recovers and which makes her incapable of living alone, somehow forcing her to accept and maintain her marriage to Pepe Sancho for 22 years during which physical and psychological abuse and also infidelities become commonplace. Fed up with the situation, María ends the relationship and decides to denounce Pepe in court, which, years later, agrees with her. But time passes and life hits María again when an intestinal obstruction leads to a coma that keeps her for three months between life and death, but which, miraculously, she ends up overcoming. After her 70th birthday party, in which she also celebrated her resurrection, María receives a new blow in her life when she is diagnosed with lung cancer against which, once again, she will have to fight as she has done throughout his life.
María Jiménez takes a look at her life, conditioned by a hitherto unknown fact: the lung cancer she suffers from and maintains a life-or-death struggle against. Despite her evident physical deterioration, María wants to take advantage of the time she has left to surround herself with her family and her friends and attends her son Alejandro's marriage proposal while remembering the most important chapters of her life. Her childhood in Seville and her difficult relationship with an alcoholic mother turn her, as a child, into a survivor; her escape to Barcelona at only 15 years old, where she knows the meaning of the word freedom and where she begins to sing professionally; the birth of her daughter Rocío when she is only 17 years old and when the girl's father refuses to recognize her; her incessant search for success that finally comes to turn her into a star, or her marriage to Pepe Sancho, who will make her go through the worst stage of her life.
