An aging group of outlaws in 1913 Texas look for one last big score, selling stolen Army rifles to a rogue Mexican general during that country's revolution, as the traditional American West is disappearing around them.

It's 1913, and the "traditional" American West is dying. Amongst the inhabitants of this dying era are a gang known as "the wild bunch." After a failed railroad office robbery, the gang heads to Mexico to do one last job. Seeing their times and lives drifting away in the 20th century, the gang takes the job and ends up in a brutally violent last stand against their enemies deemed to be corrupt, in a small Mexican town ruled by a ruthless general.
