Seeking a fresh start and a quiet life, young François journeys to an isolated sawmill tucked deep within the Pyrenees mountains to track down Gyuri, an older man who was once his mother's secret lover. Gyuri helps François secure a job at the mill, where the slow, rural rhythm initially brings peace to the workers. However, the fragile harmony of the logging community is shattered by Marie, a young local woman trapped in a stifling marriage to one of the sawmill laborers. Desperate to escape the claustrophobic valley and her unfulfilling domestic life, Marie fixes her intense desire on the newly arrived outsider. The two quickly plunge into a volatile extramarital affair, turning Marie into a cheating wife whose passionate pursuit of liberty threatens to ignite violent tensions among the tight-knit factory hands.
