Sheriff Pat Garrett (Thomas Mitchell (actor)) welcomes his old friend Doc Holliday (Walter Huston) to Lincoln, New Mexico. Doc is looking for his stolen horse and finds it in the possession of Billy the Kid (Jack Buetel). Despite this, the two gunfighters take a liking to each other, much to Pat's disgust. This does not prevent Doc from trying to steal the horse back late that night, but Billy is waiting for him outside the barn.
