An alien expedition is boldly going where no aliens have gone before: Earth! Taking on human identities, these visitors are in for culture shock of astronomical proportions as they encounter our planet's bizarre ways. Stranger still are their new physical forms, which constantly amaze them with surprises like puberty and passion, as when the High Commander (John Lithgow) becomes hopelessly infatuated with his Earthling co-worker (Jane Curtin). With sophisticated satire and wild farce, 3RD Rock From The Sun offers a hilarious look at our world from an outrageously new point of view.
