Rugged cowboy Frank Hopkins (Viggo Mortensen) is an expert horseman who performs in Buffalo Bill's Wild West Show. When affluent Sheik Riyadh (Omar Sharif), piqued by tales of Hopkins' talent, challenges Hopkins to prove himself in a treacherous long-distance horse race called the Ocean of Fire, Hopkins is forced to oblige. In the Middle East with his American mustang, he must race against thoroughbred horses ridden by the best riders in the world with his reputation -- and his life -- at stake.
