White hat: Marshal Matt Dillon as portrayed by actor James Arness. This small-town marshal has plenty to deal with: bar fights, cattle rustling, abuse and the West's grittiest outlaws. The quiet, almost vulnerable, lawman does his best to protect peace and justice in Dodge City, Kan. The job isn't easy, though, and calls for difficult decisions and good solid judgment.
Black hat: There are plenty of black hats for Dillon to deal with. His Wild West is full of complicated but inescapable truths. He can't save a girl from her abusive father, but he can throw a stagecoach robber or kidnapper in jail. Each villainous scoundrel represents a different element of the expanding American frontier.
