Paul Colten and his wife Christina moved West with dreams that were different from most settlers. Paul was a preacher who regarded the frontier as a place in great spiritual need, but, when a man the pastor was trying to help murdered Christina, Colten's idealism died amidst gunsmoke. He went after the killer and took the first step in becoming the gunfighter known as Reverend Colt. Arriving in Grayson to kill a man for money, he finds a town under the brutal control of a wealthy rancher, Leonard Caldwell. Colt befriends a former lawman whose badge was snatched away by Caldwell and finds himself in sympathy with a young couple who run the local newspaper. The Grayson Herald is printing the truth about recent killings in the town at great personal risk. Colt admires those who are standing against corruption, but the gunfighter realizes that the brutal men who rule Grayson will not be stopped by newspaper editorials alone. Reverend Colt's skills with a gun will be put to the ultimate test.
