Francisco Olivetti (Gabriel Corrado) is a prestigious lawyer whose career is based on ethics and moral values, always dedicated to defending those most in need. He lives a marriage of ups and downs with Fatima Pellegrini (Catherine Fulop), a woman who endangers the happiness of the family due to her bipolarity. They are both parents of Mercedes Olivetti (Brenda Asnicar), a somewhat spoiled girl, but with a good heart.

Francisco's life changes completely when he is faced with the case of Luz Quiroga (Aylin Prandi), a woman who is detained for having committed euthanasia with her husband, who was dying on his deathbed. Francisco is moved by Luz's story and decides to help her be exempted. Luz's goal is to regain custody of her son, who is under the care of Malvina (Maite Zumelzú), Luz's sister-in-law who hates her and who has schizophrenia problems. Among so much complicity, Francisco and Luz fall madly in love.
