After a long absence, Octavio Villarreal (César Évora) returns to Guanajuato in order to see his uncle Fernando (Joaquín Cordero), who is on his deathbed.

Octavio heads for the Villarreal mansion in his car with Marcial (Alberto Estrella), a trusted employee of Fernando, when they are intercepted by a girl on a horse.

Octavio is taken with the young woman's beauty, but the contemptuous Marcial tells him that Ana Cristina (Susana González) is Fernando's lover.

Marcial and Frida want to take over the factory and conspire so that this marriage does not last any longer than necessary, sowing doubts in Octavio's heart about the purity and good intentions of his wife.
