In the west, cacti grow abundantly while trees remain scarce. The hills become mountains when you are chasing a cow across the Sonora southwest. As the ground clears from the lack of rainfall in the summers, small thickets of shrubbery get so dense it's hard to see where they start and stop. These are the areas where the hardiest of wild cows survive and are the most difficult to catch. Mathew takes over his father's ranch when he is tragically killed. He began his taming horse career at a young age. While Mathew's Grandfather loved the wild cow hunt, his father was more inclined to taming horses. So, he followed his dream and taught his young son the craft.
As the Spinhirne Ranch grows famous for its breeding stock a man (Samuel) from south Texas comes to the desert and makes Mathew an offer, he can't refuse. The two conspire to create America's first Quarter Horse Ranch. Amid his, encounter Mathew is introduced to Steel Dust, one of the original foundation sires of every horse in North America. Nevertheless, one stallion (Cash) raised by Mathew, faces Steel Dust head-on in a match race, of which the outcome remains to be seen.
As Mathew struggles to fill his father's shoes, he meets the love of his life, faces a near-death experience on their last cattle drive, and returns home with an unexpected presence.
