For centuries, on the border of Mongolia and Russian Siberia, the nomadic tribes of the Darhat have made a living by breeding powerful semi-wild horses, which accompany them on their seasonal migrations from the steppes to the mountains. But in recent years, thieves from the Tuva tribes have been stealing their herds and selling the animals to Russian slaughterhouses for a few rubles. When his white stallion, the irreplaceable guardian of his horses against the wolves, disappears, Shukhert, a skilled rider and charismatic wrestler, sets out alone to track down the bandits and bring him back in time before winter.
