Chasing UFOs - Dirty Secrets -- (A National Geographic Documentary)

The team travels to the central California town of Fresno where frightened residents say they are being watched after they recorded a strange craft patrolling the skies. Trying to find an explanation for what these people saw, Ryder, Ben and James hear rumors of a secret military base that people suspect may be housing these mysterious craft. The search for the truth leads the team underground where they discover evidence of an underground facility. But does the team push their quest too far when they set their sights on a local military base rumored to be home to these top-secret aircraft?

The investigation begins with a video of what looks like a triangular craft moving silently over a Fresno neighborhood. They go to visit the woman who shot it to get more details and learn that she wants to remain anonymous because she believes she’s been followed ever since the sighting. The woman suspects the craft has something to do with the military and that she’s heard rumors of a secret base where they’re developing experimental craft engineered from alien hardware.
