Director Jeff Lieberman followed his horror-science fiction film Blue Sunshine with this effort, which rehashes many of the themes explored in Wes Craven's seminal horror work The Hills Have Eyes. The plot concerns a teenage land owner who heads for the mountains of Oregon with a deed to his new property and an RV full of young friends only to discover (to their extreme peril) that words on paper mean less than nothing up there... or, in the words of horticulture-loving park ranger George Kennedy, "Those mountains can't read, son." By nightfall, the youths learn the gravity of this warning, as they are set upon by a hulking Mongoloid in a knit cap and pilot's glasses who seems capable of being in two places at once.
