Dr. Bellows (Hayden Rorke) has cooked up another experiment: This time, he wants to send a male and a female astronaut to the moon. Tony (Larry Hagman) of course is chosen as the male, while an attractive scientist (Kay Reynolds) is selected as the female. Worried that the scientist will steal Tony away from her, Jeannie (Barbara Eden) turns to her wicked lookalike sister Jeannie II (also Barbara Eden) for advice--a big mistake, inasmuch as Jeannie II would like to get her claws into Tony herself! ~ Hal Erickson, Rovi
