Mork, an alien from the planet Ork on a mission to Earth to study human behavior, travels to 1970s Boulder, Colo., where he meets up with Mindy, a young journalism graduate, after his egg-shaped spacecraft lands there. The bumbling alien is trying to get a handle on Earth culture, and his frequent dispatches back to his home planet give him the opportunity to sound off on human foibles. This spinoff of "Happy Days" features Robin Williams as Mork in an early starring role for the comic actor. As Mork would say, "Na-nu, na-nu!"

Mork decides to help Mindy pay for school by selling his story to the press.

Mork invites a Russian immigrant named Sergei to live with him; Sergei calls himself an alien, which convinces Mork to register himself as one with the government's immigration department.

Mork tries to bring the true meaning of Christmas to Mindy's family.

Mork agrees to officiate at the marriage of a young friend and his girlfriend.
