An alien expedition is boldly going where no aliens have gone before: Earth!

Taking on human identities as the Solomon family, the visitors settle in Rutherford, Ohio, in order to study humankind. But they're in for a culture shock of astronomical proportions as they encounter our planets bizarre ways. Stranger still are their new physical forms, which are constantly throwing up surprises like puberty and passion - the latter especially when High Commander Dick Solomon (John Lithgow) becomes hopelessly infatuated with his human 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.

This set contains all 22 episodes from the fifth series, and sees the Solomons tackling such thorny issues as alternative sexualities, labour relations, and the complicated love life of the Big Giant Head.
