In the remote, frozen expanse of the Russian Arctic, two Komi families maintain a traditional way of life, herding 5,000 reindeer across the vast, desolate tundra. Their existence is defined by the seasonal migration of their herd, a journey that takes them across the Ural Mountains between Europe and Asia. As they navigate the harsh, unforgiving landscape, the families rely on their animals for survival, living in large, portable tents called chums. The film captures the intimate, daily rhythms of their lives, from the men's arduous work of managing the herd to the women's essential roles in maintaining the home and preparing meals. As winter approaches, the families prepare for the long, challenging migration to their winter camp, a journey that tests their resilience and deep connection to the land and their ancient traditions.
