A con man heading west to search for gold teams up with a pair of scheming brothers along the way. The trio soon find themselves in the middle of a feud between two rival families and two underhanded land developers.
A cattle-vs.-sheepman feud loses Connie Dickason her fiance, but gains her his ranch, which she determines to run alone in opposition to Frank Ivey, "boss" of the valley, whom her father Ben wanted her to marry. She hires recovering alcoholic Dave Nash as foreman and a crew of Ivey's enemies. Ivey fights back with violence and destruction, but Dave is determined to counter him legally... a feeling not shared by his associates. Connie's boast that, as a woman, she doesn't need guns proves justified, but plenty of gunplay results.
At a Mexican ranch, fugitive O'Malley and pursuing Sheriff Stribling agree to help rancher Breckenridge drive his herd into Texas where Stribling could legally arrest O'Malley, but Breckenridge's wife complicates things.

Former marshal Dolan, recently hired by Lang and Hickman as a driver, wants to stay out of the mess, but when he sees Flood's henchman Yarbrough assault Lang, he steps up to fight the corruption.
