Damnation Alley (1977)

A small group of survivors at a military installation who survived World War 3 attempt to drive across the desolate wasteland to where they hope more survivors are living. Hopefully their specially built vehicles will protect them against the freakish weather mutated plant and animal life and other dangers along the way.

Killer cockroaches, Jan Michael Vincent, Paul Winfield, George Peppard, giant scorpions, ultimate SUV's, inbred hillbilly types and dusty old Las Vegas where the slots still work…all combine to make a fun little, albeit cheesy, flick.
