深喉"The X Files" Season 1, Episode 1:Deep Throat

Mulder and Scully investigate the mental breakdown and disappearance of a U.S. Air Force officer, Col. Robert Budahas, once a well regarded test pilot. Mulder's research reveals that there is a pattern of breakdowns at Ellens Air Force base but Scully thinks there are any number legitimate medical reasons for what has happened. Mulder is soon in touch with local UFO enthusiasts and learns where in the area is best to view UFOs. He comes across two young people who regularly sneak onto the base through a hole in the fence to sit back and watch. Mulder believes the aircraft the locals are seeing were built using alien technology and it becomes apparent that the U.S. government is hiding something and will go to great lengths to keep it that way. Throughout, Mulder receives advice and a friendly warning from an unknown man, Deep Throat, who warns him to be careful and confirms Mulder's suspicions about aliens.
