To save his planet of men, an alien named Harold (Garry Shandling) is sent to Earth to procreate with a woman. But he's worlds away from understanding the opposite sex. 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 and his social skills are worse. Mix in a suspicious FAA official (John Goodman) and an underhanded co-worker (Greg Kinnear) and Harold's mission seems next to impossible. Through it all, Harold's dating game adventures are geared toward one intergalactic goal: scoring -- until he meets Ms. Right (Annette Bening).
