It's back to Perfection, NV, for munitions-crazed Graboid hunter Burt Gummer (
Michael Gross), who has made a career out of chasing and slaying the burrowing "sub-terrestrial" creatures that pop out of the ground and eat whomever happens to be standing there. This time Gummer is assisted by wisecracking cowboy Jack Sawyer (Shawn Christian), who runs a shabby theme park based on the critters, and Jodi Chang (Susan Chuang), whose convenience store is unfortunately at Graboid Ground Zero. Gummer and company have their hands full this time, when the oversized worms have mutated to a new state -- not only do they burrow, but they have wings and can fly like carnivorous dragons. Does Gummer have enough shells in his artillery cannons to knock them all from the sky? ~ Buzz McClain, All Movie Guide
