An XV-104 test plane wanders into a UFO target area and the pilot, Paul Foster, makes sightings of both the UFO and Sky One. Angry and frustrated that no one believes his story, Foster suspects a cover-up and decides to conduct his own investigation into the activities of ex-USAF Colonel Ed Straker.
