El Dorado

Cole Thornton (John Wayne), a gunslinger-for-hire, is hired by wealthy rancher Bart Jason (Ed Asner) to help him in a range war with the McDonald family in the town of El Dorado. The local sheriff, an old friend of Thornton, J.Â P. Harrah (Robert Mitchum) gives Cole more details that Jason had deliberately left out, including the possibility of having to side against Harrah. Unwilling to fight his friend, Thornton quits, to the relief of saloon owner Maudie (Charlene Holt), who is in love with Thornton (and was for a time a romantic interest of Harrah's).
The McDonalds learn of Thornton's presence in town. Fearing that he might come for them, Kevin McDonald (R.Â G. Armstrong) puts his youngest son, Luke, on guard. When Thornton passes by on his way back from rejecting Jason's offer, Luke (Johnny Crawford), who has fallen asleep, wakes and fires a wild warning shot whereupon Thornton reflexively shoots him. Luke is still alive when Thornton finds him, but he refuses treatment based upon the belief that a gut-shot man wouldn't have a chance anyway and commits suicide when Thornton turns his back on him.
Thornton subsequently brings the boy's body to the McDonald ranch and offers an explanation. The only McDonald daughter, Joey (Michele Carey), impulsively rides off before Thornton can finish his story and ambushes him shortly thereafter. Her shot is not fatal, but the bullet lodges next to Thornton's spine and in time begins to trouble him by occasionally pressing against the spinal cord, causing temporary paralysis of his right side. The local doctor, Dr. Miller (Paul Fix), does not have the skill to remove the bullet and Thornton soon departs El Dorado for a new job.
Several months later, Thornton runs into another gunslinger-for-hire named Nelson McLeod (Christopher George) and a young greenhorn with a peculiar hat called Mississippi (James Caan), who has come for revenge against one of McLeod's men for the murder of his old friend and mentor, Johnny Diamond. McLeod has been hired by Jason for the same job Thornton turned down and Thornton hears from McLeod about how Harrah has turned into a drunk after an unhappy love affair. Thornton decides to return to El Dorado, hoping to save Harrah from being gunned down by McLeod and his men. He is followed by Mississippi who also wishes to help, despite his lack of experience and terrible aim with a gun.
Once Thornton and Mississippi arrive in El Dorado, they hear more of the story behind Harrah's change. The two men then join with Deputy Sheriff Bull (Arthur Hunnicutt) in order to get Harrah sober and cleaned up. Mississippi contributes an old folk recipe for a hangover that he learned from Johnny Diamond, promising it will make any man unable to drink liquor for a while. The concoction proves to be violently effective, and leaves Harrah sober and furious. Within a day of their arrival, McLeod and his men also come to El Dorado and are hired on by Bart Jason. When one of them shoots one of the McDonalds, Thornton, Harrah, Bull and Mississippi chase the shooter and his friends into an old church and then into Jason's saloon. Harrah arrests Jason and takes him to the jail for his part in the shooting of one of the McDonalds. Later that night, Thornton and Mississippi decide to patrol the town in the hope of keeping the peace and are deputized by Bull. There is another shootout with McLeod and his men, which results in a minor leg injury for Harrah.
The next day, Maudie sends a message to Thornton and his friends, stating that McLeod's men are frightening her and her patrons. When Thornton and Mississippi go to help her, they are ambushed and Thornton has an attack that leaves him partially paralyzed and captured by McLeod. Subsequently, McLeod trades the injured Thornton for Bart Jason, a trade to which Harrah agrees, despite knowing that doing so will mean that nothing will stand in the way of McLeod going after the McDonalds.
Sure enough, McLeod and his men shortly thereafter kidnap one of the McDonalds in order to force Kevin McDonald to sign over his water rights to Jason. Thornton and the others are forced to quickly come up with a plan to rescue Kevin McDonald's son and neutralize Jason and McLeod. Despite Thornton's paralysis and Harrah's leg injury, the two of them, along with Bull and Mississippi, return to town on wagons. While Thornton distracts Jason and McLeod outside of the front of the saloon, Mississippi, Harrah and Bull attack from the rear. The kidnapped McDonald is rescued, with a little help from Joey McDonald. Jason, McLeod and his men are killed, and order is restored to El Dorado. Thornton also begins to imply that he may discontinue his wandering ways in order to stay in the town with Maudie.
