Roaming a remote plateau on the island of Sardinia, Giara horses have been at the mercy of man and nature since arriving here 2,500 years ago. They were originally brought over from Africa as farm animals but later released into the wild to fend for themselves. The horses form small herds based on family ties, while the male "father figure" battles all bachelors with designs on his harem. Now, the worst drought in 50 years threatens their very survival. Can they rise to the challenge?
