“A unique example of social cinema during the Perón era, Dark River imagines the creation of a union of exploited workers in the mate plantations in the Argentinian northeast. Paradoxically, Alfredo Varela was a Communist author languishing in prison until the filmmaker-actor Hugo de Carril, a staunch Perónist, secured his release so they could collaborate on an adaptation of his novel” (Edgardo Cozarinsky).
