In Texas in 1913, Pike Bishop, the leader of a gang of aging outlaws, is seeking retirement with one final score: the robbery of a railroad office containing a cache of silver. They are ambushed by Pike's former partner, Deke Thornton, who is leading a posse of bounty hunters hired and deputized by the railroad. A bloody shootout kills several of the gang. Pike uses a serendipitous Temperance movement parade to shield their getaway, and many citizens are killed in the crossfire.
