Peacemakers premiered on USA on July 14, 2003. The time is the late 1880's, and the Western Frontier is disappearing fast. With the advent of "forensic science" techniques coming out of places like London's Scotland Yard and New York City's police department, modern crime fighting and investigative methods are literally being invented, employed, and perfected by men and women with the vision to see that these new techniques will change the way crimes are solved forever. Civilization and the industrial age have arrived in Silver City, Colorado with a vengeance. Silver City is a tough, rugged, Rocky Mountain mining town that is indicative of the dangerous times of the Old West, populated by a rogues gallery of shady characters including thieves, criminals, hoodlums, thugs, profiteers, drifters, business tyrants, and scoundrels.
Presiding over Silver City is Federal Marshal Jared Stone, a reluctantly tough but fair and likeable man who realizes that he doesn't quite understand what this new wave of the future will bring. However, he is wise and humble enough to know that men like him - men who live by the code of the gun and the unspoken laws of the old west - are a dying breed. The winds of change are most certainly blowing... These same winds soon bring an unlikely crime fighting team into Marshal Stone's life: Larimer Finch, a young, brilliant, Scotland Yard-trained Pinkerton Agent, and clever and beautiful local mortician Katie Owen, who has left medical school to return home and run her family's mortuary business. Together, the threesome becomes a formidable crime-fighting team as they investigate various cases in and around Silver City. Stone, the people person, Finch, the technical forensics wizard, and Katie, the mortician and medical examiner, combine to bring their respective talents to bear on mysteries of all kinds - mysteries that as little as five years earlier would likely have gone unsolved, but now can be due to the new (and still evolving) modern crime-fighting techniques now available to them through forensic science.
