In the taiga forests of northern Mongolia, roughly 200 people known as the Tsaatan, or Reindeer People, live by herding domesticated reindeer through temperatures that fall to minus forty. The film follows families through the winter as they move camp, milk their reindeer, and keep canvas tents warm enough to survive in, alongside shamans who still practice rituals largely unchanged for generations. Interviews with herders describe a life measured by reindeer health and weather rather than money, and the camera stays close on daily tasks: lashing tent poles, boiling tea over open fires, tracking herds across snow that swallows footprints within minutes. Isolation is part of the story too, with only occasional contact with traders or relatives who have moved to towns, and some younger Tsaatan weighing whether to stay. The footage of reindeer moving through fog and snow, shot in genuinely harsh conditions, carries most of the film's weight, with narration filling in context rather than driving the scenes.
