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!
