The plot is very good. She arrives in town to find herself in the midst of a feud between two families. She immediately seeks out a young man from the richest family and seductively (which she is excellent at) works her way into his heart. He marries her and she is given deed to half the ranch. When her husband brings home an even richer man who owns a railroad in hopes of getting him to financially back the ranch, she convinces her husband to leave the job to her. Instead, she seduces him into falling in love with her also and talks him into buying out her husband. He agrees.
Suddenly, they find themselves totally alone as all the hands have quit the ranch. So she sends for a gunman she met by chance at the very beginning of the Western. He brings in his "boys" and they begin to take over the ranch. Finally there is the ultimate showdown between Neal, Morgan (her husband) and the gunman (Cochran).
And as I said: Patricia Neal is the dastardly darling right up to the very last breath. The role would have better suited Barbara Stanwyck or Betty Davis. But Patricia Neal it did not suit even though she did a fine job (as always). While I have seen her in many movies I shall never be able to accept her in any villain role. The Western is very good and well worth any amount of money paid to obtain it but it is just not the kind, sweet, adorable feminine Neal I am used to in movies.
