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.

Monte has a long-term relationship with prostitute Martine Bernard, while Chet has fallen under the spell of the widow who owns the hardware store. Camaraderie and competition with the other cowboys fill their days, until one of the hands, Shorty Austin, loses his job and gets involved in rustling and killing. Then Monte and Chet find that their lives on the range are inexorably redirected.
