The director's cut of the bloody, violent western from one of the masters of the genre, Sam Peckinpah. In 1913, a gang of outlaws (William Holden, Ernest Borgnine and Robert Ryan, amongst others) ride into a Texan border town where the railroad office is their target. The robbery turns into a blood-bath so the gang flee to a desert hideout where they discover that their loot is worthless. With the railroad company's hired guns snapping at their heels, they decide to escape to the apparent safety of the Mexican revolutionaries.
