Initially, it seems spliced together from two chilling classics, George Sluizer's "The Vanishing" (the original Belgian version from 1988, not the idiotic American remake) and, years before, Steven Spielberg's made-for-TV "Duel," about a psychopathic but entirely anonymous truck set on erasing a mild-mannered traveling salesman.
This could be a nice premise for an action thriller movie centered on the hero's search for hid loved one(Jonathan Mostow's "Breakdown"(1997) is a good example), but Sluizer's screenplay, based on his co-writer Tom Krabbѐ's novella "The Golden Egg", takes a more interesting route.
