Rosario's servant, Delfina (Magda Karina), essentially raises Lucrecia alongside her own son, Manuel, and they become like siblings.

Rodolfo Huerta is the teacher in the town of San Pedro; he is an upstanding and hard-working man who is married to Justina, a sensual woman who is dissatisfied with her husband's simple lifestyle, and they have two sons, Julián and Josué.

Matías Quiroga, the priest of the town of San Pedro, sees with a heavy heart that his friends are now enemies and are the principal obstacle for Lucrecia and Julián's love.

As a result of his infamy, Julián is tormented by the denizens of San Pedro, who nickname him El Chamuco (Mexican slang for "the Devil"), the pain of which he must carry for the rest of his life.

In San Pedro, Paulino suffers an economic crisis and Gabino demands Lucrecia's hand in marriage, but the very jealous Carmelo steps in and kills his father.

One day, while Lucrecia and Julián are in the fields, Lorena tries to run them over, but fails, crashes against a truck, and goes flying out the windshield; consequently, ending up with a disfigured face.

Although saddened by the loss of her family, she is joined at the river by her husband and son, whose strong blue eyes reveal him to be Julián's child, and the three live happily ever after.
