Mariana Aragón was happy to have been accepted into a prestigious gastronomy school in Paris, while Elena, her friend and roommate, shares that she is pregnant by her boyfriend Gustavo, a brave journalist.

Alejandro does not hesitate to help Mariana when he finds her injured and disoriented in the street; once in the hospital, he finds out that the girl miraculously saved her life when she manages to escape from the murderers of her dear friends.

Santiago lets Rey know his suspicions that the murder of the man recently found by his team is related to the death of Mariana's young friends.

On Rey's orders, Tuétano and Chupacabras try to assassinate Mariana in the pantheon during the burial of her friends, but Alejandro helps her escape again.

Rey appears before Mariana in the interrogation room and makes her believe that he will help her, while putting together a plan to make her appear guilty. Rey presents arguments to Alejandro that make him doubt the girl's innocence.

Mariana is tortured and Rey hires a nurse to inject her with drugs and thus make her appear to the media as an addict, for which she is admitted to the Women's Prison. Frightened, the young woman obtains the protection of Alba, an inmate who has been in prison for a long time, who is unable to prevent the new inmate from continuing to be drugged.
