This episode concerns a dinner date with Dr. Bellows (Hayden Rorke) and his wife Amanda (Emmaline Henry) where Jeannie serve the couple a bottle of rare 400-year-old wine. The beverage has a curious effect on the Bellows: namely, it renders them invisible! However, Bellows and his wife are unaware that no one can see them--and the nervous Tony (Larry Hagman) intends to keep them in the dark (so to speak) until Jeannie can figure out a solution to the current crisis. ~ Hal Erickson, Rovi
