Peacemakers depicts law enforcement efforts in Silver City, Colorado, during the waning years of the American Old West.

Deputy United States Marshal Jared Stone (Tom Berenger) and his colleague, private detective Larimer Finch (Peter O'Meara), are the primary law officers.

Katie Owen (Amy Carlson), the town's undertaker and mortician, assists them as a forensic pathologist.

To avoid reassignment to a strike breaking detail, he resigned from the agency and remained in Silver City, where he uses his knowledge of fingerprinting, ballistics, photography, chemistry and scientific analysis to aid Marshal Stone in his investigations.

Owen, a former medical student, was forced to take over the family mortuary business after the accidental deaths of her parents.
