A divorced mother, Sally (Catherine Hicks), her young son Billy (Peter Billingsley), and her new boyfriend Mike (Paul Le Mat) take a road trip through Arizona, stopping off at various tourist traps. While at a disused gold mine, Billy discovers an abandoned R.V., which he explores, unaware that the owners have been murdered by a serial killer who has been slashing travellers' throats for the past five years (and apparently cleaning up behind himself: he leaves the R.V. spotless). Inside the vehicle, Billy finds a frog-shaped medallion, which he pockets, unaware that it is a clue to the identity of the killer.
Directed by Dick Richards (producer of Tootsie), Death Valley is, for the most part, a forgettable horror/thriller that delivers very little in the way of suspense or genuine chills, Billy's perpetual peril failing to generate the intended tension. I found the kid thoroughly obnoxious and was longing for him to be bumped off; sadly, this doesn't happen. The early R.V. murders show some promise, Richards ticking both the gore and nudity boxes (a gashed throat and a smashing pair of breasts), and the later brutal slaying of a local sheriff (Wilford Brimley) with a pickaxe is both shocking and bloody, but the bulk of the film is extremely lacklustre, the biggest letdown being the death of Billy's gluttonous babysitter (Mary Steelsmith): she has her throat unconvincingly slashed with a joke shop knife (squeeze the handle to squirt fake blood) - I was at least hoping for her to be choked to death on that banana split!
The revelation that the antagonist has an equally psychotic twin is treated as a surprise, although it is clearly stated that murderous waiter Hal (Stephen McHattie) has a brother named Stu, so it's a given that he'll make an appearance at the end, just as Billy, Sally and Mike think that the horror is over. It's that predictable!
