The Outer Limits

They creep. They crawl. They kill. With the rulers of the planet Zanti threatening total annihilation unless they are allowed to exile their criminals to our world, Earth officials have no choice but to transform a remote section of the desert into an alien penal colony. But when a psychopathic intruder (Bruce Dern) stumbles across the sealed facility, he unleashes a torrent of screeching, scurrying space critters who demonstrate to the military just what the word "invasion" really means.
