- Wyatt Earp: [Opening Narration] The friendship between Marshal Wyatt Earp and Dr. John H. Holliday was one of the mysteries of Dodge City. Why Marshal Earp, a deacon in the church, could tolerate Doc Holliday was a mighty puzzle to Wyatt's friends. Doc Holliday, gambler, gunfighter, killer, had a mean disposition and a caustic tongue.

And Wyatt's insistence on making a friend of Doc Holliday finally came to a crisis between Wyatt and the men who hired him to civilize Dodge City.
