The Outlaw (1943)
Shortly after he disembarks at the Lincoln, New Mexico train depot, gunslinging gambler Doc Holliday reunites with his old friend and former partner-in-crime, Pat Garrett. When Pat, who is now the town's sheriff, hears that the penniless Doc is searching for his horse Red, who has been stolen, he directs his friend to the local dentist's office. There Doc finds Red tied up outside and confronts the young man who comes to claim the horse. Although the youth, William Bonney, an infamous gunslinger known as Billy the Kid, maintains that he bought Red from a stranger, Doc insists that he stole him.
