A young boy ("A Christmas Story" star Peter Billingsley), travelling to Arizona to visit his mother, finds an RV in the title stretch of desert filled with the grisly handiwork of a deranged killer. The bad news is, no one believes him... except the slayer, who spots the lad wearing a necklace he had left behind at the scene of his crimes. Catherine Hicks, Paul LeMat, Stephen McHattie, Edward Herrmann, and Wilford Brimley co-star. 87 min. Widescreen (Enhanced); Soundtrack: English. Region Free
