When he brings Jeannie (played by Barbara Eden) along to his ghost hunting assignment at a haunted mansion, the two soon realize that the ghost may not be what they thought it was. Meanwhile, Tony's best friend and fellow astronaut, Roger Healey (played by Bill Daily), begins dating a woman who claims to be a psychic and can communicate with ghosts.
