The Ox-Bow Incident takes place in Nevada in 1885 and begins with Art Croft (Harry Morgan) and Gil Carter (Henry Fonda) riding into the town of Bridger’s Wells. They go into Darby’s Saloon and find that the atmosphere is subdued, in part because of the recent incidents of cattle-rustling (the stealing of livestock) in the vicinity. Everyone wants to catch the thieves.
Gil learns that his former girlfriend left town at the start of the spring and drinks heavily to drown his sorrows. Art and Gil are possible rustler suspects simply because they are not often seen in town. The townspeople are wary of them, and a fight breaks out between Gil and a local rancher named Farnley (Marc Lawrence). Immediately after the fight, another man races into town on horseback, goes into the saloon and announces that a rancher named Larry Kinkaid has been murdered. The townspeople immediately form a posse to pursue the murderers, who they believe to be the cattle rustlers. The posse is told by the local judge that they must bring the presumed rustlers back alive for trial, and that their deputization by a deputy is illegal, but little heed is taken of this. Art and Gil join the posse as well, as much to avoid being its target as to participate. Davies (Harry Davenport), who is vehemently opposed to forming the posse because of its capacity for “mob rule”, also joins. Among the other people in the posse are “Major” Tetley (Frank Conroy) and his son, Gerald (William Eythe). The major informs the posse that three men with cattle bearing Kinkaid’s brand have just entered Bridger’s Pass, and therefore shouldn’t be too difficult to catch.
The men of the posse gather back in Canby’s Saloon and drink in silence. Major Tetley returns to his house and locks the door so his son cannot come in. His son yells at him through the door, telling him what he thinks of him. Major Tetley walks into another room and shoots himself. In the saloon, Gil reads Martin’s letter out loud to Art while the other members of the posse are listening. In the closing scene, mirroring the initial scene, Gil and Art ride out of town to deliver the letter to Martin’s wife and family.
