Rio (Brando) and Dad Longworth (Karl Malden) are outlaws and partners in crime. The film opens in 1880 with Rio and Dad robbing a bank in Mexico. They make their escape but stop running too soon, and the rurales swoop down on them. Dad and Rio flee into the desert, with the cops giving chase; Rio's horse is shot. With only one horse left, Dad and Rio decide that Dad will make a break for it, get a second horse, and come back for Rio. Unfortunately for Rio, once Dad makes his escape with a good horse and a bag full of gold, he decides to keep going. Rio is arrested.
Five years pass before Rio breaks out of jail. Eventually he tracks down Dad, who has not only gone straight, but has become the sheriff of Monterey, CA. Rio pretends that there are no hard feelings but secretly plots to both rob the bank in Monterey and kill Dad. Rio's desire for revenge is complicated, however, when he falls in love with Dad's beautiful stepdaughter Louisa.
