In the remote, sun-scorched villages of the southern highlands, a creeping dread takes root in Oscuridad del Sur. The film follows a disparate group of locals, including the skeptical farmer played by Waldo Facco and the increasingly fearful Ximena del Solar, as they confront a series of inexplicable and violent events that defy rational explanation. Their community, already strained by isolation, begins to fracture under the weight of a malevolent force that seems to feed on their deepest anxieties and historical secrets. Directed by João Augusto de Nardo, Oscar Lopera, and Sergio Arroyo, this atmospheric horror tale weaves a chilling narrative where the landscape itself becomes a character, and the line between superstition and terrifying reality completely dissolves. As the darkness tightens its grip, each character, from the resilient Luna Balvanera to the enigmatic outsider portrayed by Michael Collins, must face a primal evil that challenges their sanity and survival, promising a descent into a uniquely unsettling folklore-inspired nightmare.
