Answer:
In the town of Rio Bravo, Texas, sheriff's deputy Dude (Dean Martin), who has acquired the contemptuous nickname Borrachon (pronounced:[bo.raton], Spanish for "big drunk"), enters a saloon but cannot afford a drink. Joe Burdette (Claude Akins), brother of rancher Nathan Burdette, tosses a silver dollar into a spittoon. Presidio County, Texas, Sheriff John T. Chance (John Wayne) appears and kicks the spittoon away, looking at Dude with disgust. Dude is shamed by his plight and takes out his anger on Chance, knocking him out with an ax handle. Joe begins punching Dude, then shoots and kills an unarmed bystander who tries to intervene.Joe heads to his brother's saloon, where a bloody Chance comes to arrest him for the murder of the bystander. Another patron draws his gun on Chance, but Dude shoots the gun out of the man's hand. Joe is locked up in the local jail. Chance is willing to deputize Dude, provided he can stay sober. Both remember how good with a gun Dude used to be.Chance's friend Pat Wheeler (Ward Bond) and his wagon train of supplies stop in town, with a young gunslinger, Colorado Ryan (Ricky Nelson), riding guard. Inside the jail, Stumpy (Walter Brennan), Chance's game-legged deputy, keeps watch over the jail and Joe, who knows that Stumpy holds an old grudge against Joe's wealthy and powerful brother. Joe warns his jailers that Nathan Burdette will not like how his brother's being treated.A mysterious woman nicknamed Feathers (Angie Dickinson) is in the saloon, playing poker. In the meantime, Dude and Chance patrol the town. Hotel owner Carlos (Pedro Gonzalez-Gonzalez) stops the sheriff, saying Wheeler has been talking too much about Chance needing help. In the saloon, Chance implores Wheeler to stop, as it will draw attention from the wrong people. Wheeler suggests that Colorado could be of assistance, but Colorado politely declines, saying he wants to "mind my own business." Colorado also promises not to start any trouble without telling the sheriff first.Feathers leaves the poker game...
