To save his planet of men, an alien (Garry Shandling) is sent to earth to procreate with a woman. But he''s worlds away from understanding the opposite sex. Once on earth, he assumes his human identity as Harold, armed with dating lessons from his home planet, but the only thing he''s courting is disaster. As he hits on every female in sight, he runs into one technical difficulty...his \"member\" buzzes when he''s aroused. On top of that, his pick-up lines are bad, his social skills are worse and his mating chances are slim to none. Mix in a suspicious FAA official (John Goodman) who''s on his heels, and an underhanded co-worker (Greg Kinnear) who''s on his back, Harold''s mission seems next to impossible. Until he meets Ms. Right (Annette Bening). Now, an extraterrestrial and a human tie the knot, and unravel the universe. Through it all, Harold''s dating game adventures are geared toward one intergalactic goal: scoring.
