Mork's boss, Orson, assigns Mork to study the planet Earth. After landing near Boulder, Colorado, he meets Mindy McConnell who was stranded in the woods by her lecherous boyfriend. Thinking Mork is a priest, Mindy lets Mork escort her home. However, when they are back at Mindy's apartment she discovers that he is an alien. Later, in a flashback sequence, Mork tells Mindy about a previous visit to Earth when Fonzie arranged a date for him with Laverne De Fazio.

After constant hounding from Fred, Mork agrees to move out of Mindy's apartment. But Mork's plans are complicated when he becomes drunk on ginger ale.
