NATURE: Cloud: Challenge Of The Stallions

The continuing saga of Cloud, the wild, white stallion, returns viewers to the Arrowhead Mountains of Montana. Cloud is now a confident band stallion in his prime. As he rules the mountains, gathering mares and expanding his reign, the story turns to his two sons.

Bolder is his by birth — beautiful and golden, the success of his father and grandfather flowing in his veins. Flint, sired by another stallion, is the colt Cloud raised.

Now, Bolder has gathered some mares of his own, while Flint has joined a group of bachelor stallions, young guns roaming the mountains. Who will rise to challenge the mighty Cloud? Will nature or nurture produce the next great stallion of the Arrowheads?

This poignant and engrossing chronicle explores the challenges presented not only by ambitious sons, but also by the harsh mountain weather, deadly mountain lion attacks, and the changing relationships within and between bands of wild horses in the mountains.

The film also touches upon the effect of the on-going efforts of the Bureau of Land Management (the BLM) to administer a program of population control, including infertility drugs and bait trapping, to remove animals from the mountains.

It is yet another hurdle that Cloud and his family and the rest of the horses in the Arrowheads must overcome in the day-to-day efforts to survive in the wilderness.
