In Mexico, expatriate American pistoleroMartin Brady is employed by the Castro brothers, Marcos, a general, and Don Cipriano, the new governor. On a business trip to the United States to arrange the purchase of a wagonload of rifles and ammunition, he is delayed when he breaks his leg in an accident in the Texas border town of Puerto. Treated by Dr Stovall, he stays with German immigrant Ben Sterner, who is the seller of the rifles, and Ben's nephew Ludwig. Brady's help is sought by the local U.S. Army commander, Major Colton, to persuade Cipriano Castro to cooperate with Colton's Buffalo Soldiers in an expedition against hostile Apaches in Mexico. In the meantime the rifles he purchased for Castro have been stolen. Captain Rucker of the Texas Rangers knows that Brady fled to Mexico as an adolescent after avenging the murder of his father not knowing the man he killed was an outlaw, and tries to enlist him as a Ranger. Brady is attracted to Colton's unhappy wife Ellen, but after shooting a man who murdered Ludwig and then drew on Brady, he returns to Mexico to inform Cipriano Castro of the missing rifles. Major Colton and Ellen arrive to meet with Cipriano, arranged by Travis Hight, the representative of a railroad threatened by the Apaches. Ellen and Brady have a brief affair. Cipriano tells Brady that by law he must pay a debt for the rifles and orders him to assassinate his brother Marcos, who seeks to make himself governor instead. Brady refuses and finds himself an outlaw in Mexico as well. Weeks later on the run, he finds cavalry sergeant Tobe Sutton and returns with him to Major Colton's camp. Colton has been seriously wounded in a skirmish with the Apaches but is determined to rendezvous with Captain Rucker and General Castro's troops. En route they recover the stolen rifles from a small band of Apaches, but Colton dies. The rifles are returned to General Marcos, who reveals that Cipriano is also dead and he is now governor. Calling Brady an assassin, he demands the Americans surrender him and leave Mexico immediately. However Rucker offers to help Brady prove that the shooting in Puerto was a case of self-defense if he returns to Texas. Brady decides to risk it and heads towards the Rio Grande to be with Ellen. Near the river he is ambushed by a gunfighter frequently seen with Marcos. Brady kills him but his Andalusian stallion, a constant companion throughout the story, is killed. Brady leaves his gun, bullets and sombrero by the horse and walks towards the U.S.
went to Tom Lea and asked if he could direct it. The only money that Lea received from the picture was for his role as the barber. The motion picture was filmed in the state of Durango. Parrish and Lea first asked Henry Fonda, then Gregory Peck to take the starring role. But, Mitchum really wanted to do the film, and after Fonda and Peck said no, Mitchum took over production. During filming in Durango, Mitchum and his stunt double Chuck Roberson decided to have a few drinks at a local cantina. They witnessed two Mexicans get into a violent confrontation in which one drew a pistol and fired a shot into the other's face. After running outside momentarily, the wounded man came back into the bar and dropped dead. The incident shook up Mitchum so badly it convinced him to keep his drinking to the hotel and its vicinity.
Reception
The film was not well received at the box office and by some critics, but other critics considered it beautifully filmed, by cinematographers Floyd Crosby and Alex Phillips. A rave review in the New York Times appeared on Nov. 5, 1959, critic Howard Thompson referring to Mitchum as "ideally cast" and writing: "This is a superior, intelligent film on nearly every count... beautifully paced by Robert Parrish's direction and magnificently evocative of the locale where it was made, this Chester Erskine production is consistently rewarding." Upon its release, TIME said about it: "But the result is just a crying Shane. All that is truly dramatic is the wonderful country itself" and about Mitchum's performance: "...he sounds like an Aztec exchange student after six terms at C.C.N.Y.". "The rest of the plot is as snarled as a ball of tumbleweed." and; "...a western that is more woolly than wild". Upon its 1961 release in Cuba, it set off an ideological fury due to "two Mexican bandits who were named the Castro brothers". As Roger Fristoe notes, recent critics regard the film more highly than critics writing more than fifty years ago. Dennis Schwartz wrote in 2009 that the film is "A wonderfully rich western that ambitiously covers many familiar themes and does a good job in developing the main character and his knotty personality."
