A herd of chemically altered rattlesnakes become fearsome killers in this made-for-TV chiller. The tale is set in the Mojave Desert and centers upon Sam Parkinson, a noted zoologist, who has come to investigate a series of strange deaths that began with two dead children found near their parents' campsites. Sam is accompanied by Ann, a photographer who make an appalling discovery. ~ Sandra Brennan, All Movie Guide
