The story, set at the end of the 19th century, revolves around the rivalry between two families of ancient peasant lineage, the Valladares and the evil Vilches who, out of greed and sentimental revenge, try to dispossess the true owners of their land. The Valladares defend theirs, ending the conflict with a melee between the two main rivals. There are duels, fires, chases, kidnappings, betrayals and deaths. There is also a romantic note, the costumbrista landscape, the laughable moment and the folk songs.
Baltasar, a young man in his twenties, is sent by his father to live with his aunt Dolores, an elderly widow and childless widow, on the Las Pataguas farm. There he meets his neighbors, the Araneda family, owners of the El Pantano farm and parents of the beautiful Humilde, with whom Balthazar falls in love. But the girl is "bewitched" by Saúl Araneda, her seductive cousin, whom the locals consider dangerously jealous.
