Western legends Pat Garrett, Doc Holliday and Billy the Kid are played against each other over the law and the attentions of vivacious country vixen Rio McDonald.
Newly appointed sheriff Pat Garrett is pleased when his old friend Doc Holliday arrives in Lincoln, New Mexico on the stage. Doc is trailing his stolen horse, and it is discovered in the possession of Billy the Kid. In a surprising turnaround, Billy and Doc become friends. This causes the friendship between Doc and Pat to cool. The odd relationship between Doc and Billy grows stranger when Doc hides Billy at his girl, Rio's, place after Billy is shot.
