Dick receives an unpleasant order from the home planet on the hour-long third-season opener: he must marry the Big Giant Head's niece Janet. As Sally, Harry and Tommy escort Janet on the rocket to Earth, the bride-to-be sets out to prove that she's a true domestic goddess, brushing up on her skills by reading The Joy of Cooking, The Joy of Sex - and The Joy of Yiddish. But a defiant Dick is sticking by Mary; whether Mary will stick by Dick is another question. Meanwhile, Janet's arrival in Rutherford is anything but quiet: Officer Don suspects that aliens have landed.
3RD ROCK FROM THE SUN is an inspired half-hour comedy series farcically dealing with the human condition set in the fictional city of Rutherford, Ohio. This gentle-hearted series stars John Lithgow as the High Commander of an investigative team sent to Earth on a mission to learn everything about humans and their so-called advanced civilization. Described by its producers as 'Carl Sagan meets the Marx Brothers', 3rd Rock has a clever, distinct point of view seen through the extraterrestrial team who has no other worldly powers except absolute truthfulness.
