La Rodeille is a documentary that explores an ancient tradition from northern Catalonia, in southern France, through an emblematic candle. This candle is associated with a Pyrenean myth: the story of a shepherd who allegedly repelled three hail clouds, called calabruixa, thus saving the harvests of the valley. This narrative, deeply rooted in local culture and imbued with Catholic symbolism, continues to resonate in the region. The film navigates between family history, local tradition, and scientific exploration to provide an intimate look at the relationship between humans and the mastery of nature. Combining biographical elements and historical narration, *La Rodeille* questions the boundaries between belief and knowledge, showing how ancient rituals attempt to tame the forces of the environment while perpetuating collective and personal narratives.
