The most acclaimed film by one of classic Argentine cinema’s foremost directors, Mario Soffici’s gut-punching work of social realism, shot on location in the dense, sweltering jungle of the Misiones region, simmers with rage against the oppression of workers. A group of desperate men are conscripted into indentured labor on a treacherous, disease-ridden yerba maté plantation under the control of the brutal foreman Köhner (Francisco Petrone)—a situation that boils over in an explosive act of rebellion led by the defiant Podeley (Ángel Magaña), and made all the more tense by the fact that Köhner and Podeley love the same woman: Andrea (Elisa Galvé), the sweet-spirited daughter of the camp’s doctor. The expressionistic, shadow-sculpted cinematography of Pablo Tabernero evokes the feverish dread of a place where suffocating heat, economic exploitation, and unremitting cruelty lead inexorably to madness and violence.
