The Jeffersonian's Dr. Jack Hodgins ropes Walter into searching for an 'Alien' Spacecraft that was seen and videoed by a pilot of an incoming Space Shuttle who is now dead (due to him not keeping quiet), thereby getting the other pilot, Col. Bradshaw's life back after he was discredited by a shadowy government agency. But all is not as it seems and Walter's life, family and friends face a very real threat from a woman code named 'Pope' (guest star Peta Wilson). Meanwhile Willa and Timo attempt to get their marriage arrangement dissolved by the notorious Uncle Shad. (guest star Eric Roberts)
