In the wilds of Siberia, a group of reindeer herders guide their animals across the bleak terrain. Suddenly, a vast hole appears in the ground beneath their feet. The men must rely on their strength, and a large slice of luck, to prevent themselves from tumbling down into the depths below.

Their attention was first drawn to Siberia, the remote Russian state that covers most of northern Asia, in July 2014. A helicopter pilot flying near the Bovanenkovo gas field on the Yamal Peninsula had spotted something unusual down below.
