A journey to help thousands of horses and revive an ancient tradition

Filmmaker Kasimir Burgess travelled to Mongolia to follow two young men on their gruelling journey to bring 2000 horses across the Steppes to fresh pastures during an exceptionally brutal winter.

For centuries, the herders of Tsakhir Valley in Mongolia have protected their horses from the harsh winters by nominating their bravest young men to move them.

But the ancient practice has been forced to stop in recent years due to climate change.  Iron Winter documents one community's attempt to revive the tradition by initiating two friends into a rite of passage in danger of being lost.
