Isle of the Snake People

First it's two adorable little boys, fanged to death by at least a dozen of 'em while camping with their parents. Then a housewife is greeted by an army of wriggling horrors scurrying around her feet. Worse, as a plumber crawls beneath a home and disconnects a bathtub drain pipe, a big scaly one makes a beeline straight up his pants! The unaware lady of the house then climbs into a relaxing bubble bath, only to find rattlers suddenly swimming between her legs! (official distributor synopsis)
