A mysterious drifter named Paul and his dog Abbie make their way towards Mexico through the barren desert of the old west. In an attempt to shorten their journey they cut through the center of a large valley - landing themselves in the forgotten town of Denton - a place now dubbed by locals as a "valley of violence." The once popular mining town is nearly abandoned, and controlled by a brash group of misfits and nitwits - chief among them, the seemingly untouchable, Gilly who is the troublemaking son of the town's unforgiving Marshal. As tensions rise between Paul and Gilly, Denton's remaining residents bear witness to an inevitable act of violence that starts a disastrous chain reaction, infecting the petty lives of all involved and quickly drags the whole town into the bloody crosshairs of revenge.
