It's summer solstice in Siberia, a time of endless daylight and extraordinary festivals. Bruce Parry journeys to meet the Sakha horse people and a remote encampment of Eveny reindeer herders in the wild Verkhoyansk Mountains, where he finds out how they are embracing the challenges of a post-Soviet Arctic. For Bruce, it's also a journey of personal discovery as he goes in search of the ancient shamanic religion of these wild northern lands.
