Three outsiders arrive at Ribeiro de Baixo, a village on the northern highlands of Portugal, where mysterious night lights foretell the death of its inhabitants. In the silence of the valley, two women, Áurea and Umbelina spend their days watching over the cattle across the border, sharing tales of encounters with wolves and ancient traditions. From France, grandchildren arrive, leisurely joining the village in witnessing the twilight of a generation and a way of life.
