Audie Murphy may have had top billing in Ride Clear of Diablo, but the film is bushwhacked and stolen by co-star Dan Duryea. As notorious gunslinger Whitey Kincaid, Duryea is hired by sinister forces to kill Murphy, who is out to avenge the murders of his father and brother. Instead, Kincaid befriends Murphy, and helps him track down his family's killers. Since Murphy is the star, it is he who exacts final vengeance, but the script makes clear that he couldn't have done this without the aid of the snide, smirking Kincaid. Ride Clear of Diablo's supporting cast includes singer Abbe Lane, who handles her "bad girl" role with class.
