Tribulation 99: Alien Anomalies Under America

In the year 1000, aliens from the planet Quetzalcoatl flee their dying planet and take refuge under the Earth's surface. Disturbed by 1950s American atomic testing, the aliens strike back at the USA in such varied schemes as the replicant Castro, the psychic vampire regime in Grenada and the Allende plot to alter the Earth's axis. Only covert action by the CIA can stop the dreaded Quetzals. (imdb)
