Backlash
Jim Slater (Richard Widmark) meets Karyl Orton (Donna Reed) in Gila Valley, Arizona. She thinks that he is searching for a gold cache believed to hidden somewhere in the valley. When a man with a rifle starts shooting at him, Jim wonders if she can be trusted. After Jim kills his foe, he discovers the dead man was a deputy sheriff from Silver City. He takes the body there.
When Sheriff J. C. Marson (Edward Platt) questions him, Jim reveals that he is after the person responsible for his father's death. Jim's father and four other men were besieged and killed by Apaches. Jim believes there was a sixth man who got away and could have gone for help, but instead decided he wanted the gold they found all to himself. Marston reveals that one of the men was the brother of the dead deputy. There are two other brothers, who will want revenge. When Jim refuses to leave town, Marston suggests he go see Sergeant George Lake (Barton MacLane) in Tucson. Lake led the detail that found the massacre victims.
Jim takes his advice, but finds Lake and his men under siege at an isolated trading post. Lake tells Karyl that only three of the bodies could be identified. While there, Karyl stakes her claim to the gold; her husband was another victim of Gila Valley. Lake and Jim sneak out that night and stampede the Apaches' horses, allowing the party to escape. Lake, however, is mortally wounded. Before he dies, he reveals they found a horse bearing the brand of Carson's outfit in Texas.
When Jim returns to Tucson, he encounters Karyl in a hotel, being forced upstairs by a stranger. Karyl calls him by name, whereupon the stranger draws his gun. Jim kills him and wounds another man gunning for him, though he himself is shot in the shoulder. Afterward, Karyl reveals that the dead man is Jeff Welker (Robert J. Wilke) and the survivor his brother Tony (Harry Morgan). Jim slaps her. She tracks him down, tends to his wound, and offers to trade information. Jim kisses her.
When the pair reach their destination, Major Carson (Roy Roberts) tries to recruit Jim against Bonniwell (John McIntire), who has organized the local bandits. Jim is not interested in the upcoming range war, though he does learn that Bonniwell arrived in the region with $60,000, the same amount as the missing gold. One of Carson's gunmen, Johnny Cool (William Campbell), informs Bonniwell of Carson's plans.
Bonniwell gathers his men in town, guns down Sheriff Olson (Robert Foulk) when he tries to keep the peace, and prepares an ambush. He finds Jim locked in the jail. He lets the prisoner out when he learns who he is, then reveals that he is Jim's father, whom Jim had not seen since he was a child. The gold came, not from mining, but via robbery. The others forced Bonniwell out, only to run afoul of the Apaches, leaving him to collect the gold. Disillusioned, Jim wants nothing to do with his father.
Karyl pleads with Jim to leave now, but he wants to warn Carson. When he tries to fire a warning shot, he discovers that Bonniwell gave him back an unloaded gun. Bonniwell chases his son with a knife, but Jim manages to wrestle a gun from one of the bandits and fire. Alerted, Carson has his men surround the town, whereupon the bandits panic and flee. Bonniwell offers to step out of hiding and draw to see which Slater is faster, but he treacherously already has his gun in his hand. Fortunately, Carson's men ride in and fatally shoot him just before Jim steps out in the open.
