An alternate title for this movie could easily be RV to Hell. Two middle-class couples take their spankin'-new motor home on a trip to Colorado. While camping out in Texas, the men see something they shouldn't--a human sacrifice by Satanists who somehow manage not to notice their Safeway-sized vehicle until the last minute. The tourists flee from the devil-worshippers, getting the monstrous RV hung up in a stream, and so goes the rest of the movie. The local sheriff is in league with the devil, and every town they come to is full of pesky Satanists. The holidaying couples are nothing if not resourceful, though; when a pair of determined Beelzebubbers cling to the vehicle like barnacles, Peter Fonda pokes at them with an aluminium vacuum-cleaner wand until they give up and fall off! Oddly, halfway through the film, it turns from a fairly routine (if suspenseful) horror movie to a Ron Howard-style car-chase film, with half a dozen vehicles pursuing the motor home. The holiday-makers continue to abuse the RV until large chunks of it begin to fall off, fending off their enemies with a shotgun until the nasty surprise ending. With a cast that includes Fonda, Warren Oates, Loretta Swit, and Lara Parker, it's hard to go wrong (though the women's roles consist of screaming ineffectually, making coffee, and cleaning the earth-toned Winnebago). Yep, this Central Texas-lensed drive-in feature supplies thrills, car wrecks, devil-worshippers, and unintended laughs by the bushel... what else can you ask for? --Jerry Renshaw,
