"Sometimes the body has a mind of its own."
"The first bite is the deepest."
Snakes at the Yellow Sands Nuclear Base in Arizona are somehow contaminated. According to one desert psycho they are trying to get away from the area but they're confused so they gather in huge groups in the middle of the road. In what could have been the best road cruising day ever, instead, our protagonists run them over by the dozen. It looks like they used some real ones in the mix, because some were moving and some were squirting blood when they got run over. Those could have been faked too, but this turkey looks so low budget that it might have been cheaper to use the real thing. For some reason never explained when the snakes bite someone, parts of them start turing into snakes - their hands, their tongues, and maybe others we don't see. Lots of different real snakes were used here along with some pretty terrible fakes, including corn snakes, water snakes, rattlesnakes, ratsnakes, gophersnakes, ball pythons, boa constrictors, and kingsnakes.
