The Last Puestero is a short documentary that tells the story of Adonai, a gaucho -or Argentine cowboy- who spends most of his days alone in a remote Patagonian outpost, protecting cattle from poachers and pumas. While deeply proud of his work and the skills it demands, he struggles with the loneliness of being away from his wife and children in town. As he hopes his son will carry on the puestero tradition, he faces the painful reality that changing times may bring an end to this way of life.
