1860: The Pony Express ran on the sweat and blood of headstrong young trailblazers. Fighting hostile Indian and greedy White Man alike, the Express Riders forged a perilous trail as they carried the U.S. Mail through the untamed wilderness from Missouri to California. Morgan Bunker, a daring young rider for the Pony Express, fought for his life and soul to resist the seductive and determined Widow McPhee, owner of the rival Ace Freighters. In her quest for money and power, the scheming temptress first plotted Morgan's death, and later committed an unspeakable sin—in a ruthless plot to sabotage the Pony Express and steal away the coveted U.S. Mail contract. As this bitter rivalry raged to a peak, two brothers riding for enemy freight companies were torn apart by conflicting loyalties, and found themselves locked in a no-holds-barred fight for power, glory and the ultimate prize—the love of a passionate young beauty.
