On the outskirts of town, the hard-nosed Vienna (Joan Crawford) owns a saloon frequented by the undesirables of the region, including Dancin' Kid (Scott Brady) and his gang. Another patron of Vienna's establishment is Johnny Guitar (Sterling Hayden), a former gunslinger and her lover. When a heist is pulled in town that results in a man's death, Emma Small (Mercedes McCambridge), Vienna's rival, rallies the townsfolk to take revenge on Vienna's saloon -- even without proof of her wrongdoing.
