A group of travelers are menaced by an unseen force in this chilling, supernatural horror tale. A truck driver, a schoolboy, a retired bank manager, and an eccentric country woman are among the group thrown together on the Silver City Highway—where they are able to go neither forward or backward—on a nightmarish journey that won't end. And when they run out of gas, the land seems to funnel them towards a homestead where a number of gory murders have occurred. Told from shifting perspectives by characters who seem to be hiding something, suspense builds as the group collapses under the escalating stress.
