Sighting 4002: The Joshua Flats IncidentAfter several prominent citizens of Joshua Flats report seeing a U.F.O., Air Force investigators turn, after getting nowhere with the adults, to a frightened 11-year old boy. Gatlin and Fitz try to investigate the reported sightings, but are hindered by curious sightseers and townspeople who are reluctant to reveal any information. Trying to determine whether or not the sightings were a hoax, Gatlin and Fitz surmise that the answer might lie with young Pauley Ramirez, if he would only break his silence.
