Petronella - Das Geheimnis der Berge

Set against the jagged, unforgiving peaks of the Swiss Alps, Petronella - Das Geheimnis der Berge is a psychological study of isolation and the crushing weight of ancestral superstition. The narrative follows the titular Petronella, a young woman living in a remote mountain village where survival depends entirely on the 'Bisse'—an ancient, precarious water channel carved into the cliffside. When the water stops flowing, the villagers succumb to a dark, pagan belief that the mountain demands a human sacrifice to restore its bounty. Petronella finds herself at the center of this spiritual storm, caught between her burgeoning desire for a life beyond the ridges and the rigid, often cruel expectations of her community. As the village elders, led by figures of terrifyingly stoic resolve, push for a return to old ways, the film explores whether modern love can survive in a place where the earth itself seems to demand blood. It is a story of engineering versus myth, and the terrifying silence of the heights.
