In 1979, a rare breed of rattle snake – naturally, a more ferocious variety than the typical species – is set loose after the truck carrying it overturns. After fatally striking both the occupants of the crash, it then descends on a disused mine shaft where it breeds with regular rattlesnakes, and 20 years later the effects of this lethal concoction are awoken by a housing development. Harry Hamlin is the new fire chief whose first day on the job sees him dealing with a fatal snake bite, after a pair of juveniles frolicking in a thicket stumble on a specimen. From there, matters deteriorate as locals are overcome by a plethora of the new breed, the venom from which is more deadly than any known to man, and predictably, for which no serum currently exists. A herpetologist is enlisted but with the local economy's purse strings being controlled by greedy developer (Scalia), action is far from swift or decisive. So, inevitably, several bystanders quickly become victims until Scalia decides to take matters into his own hands, with disastrous results.
Not bad for a tele-movie, with capable performances and well conceived sub plots. McCormack as the local snake enthusiast comes off best, in spite of her whacky idea to address the problem by introducing more snakes, while Scalia plays a remarkably restrained villain, whose worst trait is being unethical moreover than exhibiting any overtly sinister behaviour. The blossoming romance between Hamlin and Sturges offers gentle respite in the film's troughs, and generally speaking, the show moves along with reasonable momentum and pace. While the special effects aren't all that special, director Nosseck still manages to build the suspense and an effective balance between storyline and detail. Perhaps the only real faux pas is the film's title – unless fitted with a silencer, one would assume that rattlesnakes indeed rattle, and would therefore only be silent to the hearing impaired.
A sharp eye for detail will reveal that the location is clearly not the USA in which the picture is set, but actually Queensland, Australia, as such the peripheral cast will be familiar to Australian audiences with familiar faces in bit parts and some supporting roles. Not movie of the week material, but competent within in its own limitations and definitely worth a look for those who don't suffer from snake phobia.
