Lust for Gold
In modern times, a newspaper reports that "noted explorer and writer" Floyd Buckley (Hayden Rorke) claims to have discovered the location of the lost gold mine. He is approached by Barry Storm (William Prince), who believes he has some claim to it, as the Dutchman was his grandfather. Buckley brushes him off, but when he heads into the Superstition Mountains, Storm secretly follows him.
However, an unseen killer shoots Buckley, making him the fourth recent murder victim. Storm notifies Sheriff Early (Paul Ford) and his deputies Covin (Will Geer) and Walter (Jay Silverheels). Covin tells Storm more about the mine; a hundred years before, Pedro Peralta had hidden $20 million in gold in the most inaccessible of his mines, only to be killed by the Apaches for defiling a place holy to their "thunder god". His greed whetted, Storm investigates further.
A flashback follows. In 1880, Jacob "Dutchy" Walz (Glenn Ford) and his friend Wiser (Edgar Buchanan) overhear Ludi (Arthur Hunnicutt) carelessly call his companion "Peralta" (Antonio Moreno). Recognizing the name, they trail the pair into the mountains. After Ramon Peralta finds his brother's mine, Walz and Wiser gun the two other men down in cold blood; then Walz treacherously shoots Wiser too.
When Walz returns to Phoenix with huge gold nuggets, the news spreads quickly. Scheming, discontented Julia Thomas (Ida Lupino) becomes acquainted with Walz, without telling him she is married to Pete (Gig Young). His suspicions of her motives are allayed by the fact that she can speak German. They soon fall in love. When she finally tells him about her husband, Walz gives her money to bribe Pete into giving her a divorce. However, Walz later learns that Julia has lied to him repeatedly. Unseen, he watches as Julia placates her husband by telling him she will soon learn the location of the mine.
Walz gives Julia directions to the treasure. Though Julia seems to care for Walz, Pete forces her to show him the map. When the couple reach the mine, Walz pins them down with his rifle. In the ensuing gunfight, Pete eventually runs out of bullets. Walz cruelly toys with them, letting them go without water. Finally, Julia stabs Pete in the back and pleads with Walz to believe she loves him. Before he can act, an earthquake triggers a rockfall that crushes her and closes the mine.
The film returns to the present. Storm has uncovered enough information that he believes he knows where the mine is. When he gets to the key landmark, he encounters Covin, who pulls a gun on him. It turns out that the deputy has been searching for the mine for twenty years and has been disposing of his competitors. A fight breaks out; Covin is about to push Storm off the mountain when a poisonous snake bites him; he falls to his death. Afterwards, Sheriff Early points out that, even with the new clue, Storm does not know the exact location and would have to dig up the entire mountainside. At that point, Storm gives up the search.
