From the liner notes

When four friends embark on a road trip to Vegas looking for fun and a few cheap thrills, they have no idea that they're about to fall into a blood-drenched charnel house of tension, torture, and the darkest depths of pure primal fear! After their car breaks down in the middle of nowhere, they must find a way back to civilization. But their plan soon arouses the malice of Rusty Nail - a murderous, vengeful trucker with an insatiable appetite for gruesome mutilation and sadistic pain - and he'll stop at nothing to ensure they pay their toll...one body part at a time!
