In the remote, frozen reaches of northern Mongolia, a small community of Tsaatan nomads struggles to maintain their ancient, reindeer-herding way of life. As the modern world encroaches, the Tsaatan face the difficult challenge of balancing their traditional existence with the demands of a changing society, particularly the requirement for their children to attend school. Through the eyes of one family, the film captures the profound connection between the Tsaatan and their reindeer, the harsh realities of their environment, and the poignant sacrifices they make to preserve their culture for future generations.
