El valle de los miserables_

In 1909, former judge Cristóbal Zamarripa owns Valle Nacional, a tobacco plantation where he exploits workers with the support of the tyrant Porfirio Díaz, who sends him political prisoners as slaves. The others are lured with the promise of high wages, but end up owing everything to the company store. All are tortured, raped, or killed when they protest. Another landowner whose brother was killed by Zamarripa and who falls in love with one of his daughters is going to be punished, but he flees and becomes a revolutionary.
