On the banks of the San Francisco River, two families have been competing for many years. They both produce cotton. Colonel Hasintu desires to seize the lands of the Dos Anjos family. And one day, during an argument, Colonel Hasintu dies, and in his place the head of the family becomes Afranio, his son. Afranio never liked the way his father ran things, and he decided that he would not become as domineering as his father. He falls in love with Leonor, and despite her being from a poor background, he marries her. They have a daughter — Maria Teresa. However, power and money did their work — Afranio also continues his father's fight for the lands. It went on for many years. And his daughter Maria Teresa falls in love with Santo, one of the sons of Dos Anjos. But will the young couple, despite the feud between their families, be able to be together?
