After the marriage Donoso starts experiencing agitated strange nightmares with recurrent scenes of peasant and country life and a woman calling "Salvador" in the distance.
Meanwhile his new wife, Isabel Arroyo (Amparo Grisales) plots to poison him and inherit. Aided by her lover, company executive and Donoso´s protégée, Andres Coronado (Armando Gutierrez)[6] with whom she plans to remarry.

Salvador uses his closeness and manipulates inside knowledge to enamour Isabel. A tormentous love affair ensues. Salvador regains control of his wealth and remarries Isabel to later reveal to his daughter that she was not the cause of his stroke and reveal his true murderers and die.[8][9]
