Circuit judge John Goodnight (Luke Perry) travels throughout the western territory in the 1880s presiding over legal cases in small towns. An honorable man, Goodnight is dedicated to dispensing justice, one town at a time, and protecting the innocent from injustice. Con artist Lucy Truffaut (Katharine Isabelle) earns her money as a card sharp and sells unsuspecting investors fake money-printing machines. One victim of her confidence game, Colonel Cyril Knox (Ricky Schroder), catches up with her and prepares to take his revenge. Just as he's about to take her away, she surrenders to a Pinkerton detective who arrests her after he confirms that she is wanted for larceny and fraud. The detective informs Knox he's taking her to Fort Collins to be remanded to federal authorities.
