It has been many years since wild horses roamed the grassy plains of western China. It is a land of harsh extremes, where a herd's survival can only be assured by a strong and worthy leader. Wind Chaser is the first wild stallion to lead a herd here in nearly half a century, as scientists attempt to reintroduce the Przewalski horse back into the wild. Rarer than the giant panda, this small but robust horse must overcome severe challenges including summer drought, winter cold and ferocious predators in order to secure the survival of their species. Follow Wind Chaser and his herd as they attempt to conquer the weather, new surroundings and internal squabbling in this extraordinary drama of nature.
