The adventures of two amiably aimless metal-head friends, Wayne and Garth. From Wayne's basement, the pair broadcast a talk-show called "Wayne's World" on local public access television. The show comes to the attention of a sleazy network executive who wants to produce a big-budget version of "Wayne's World"—and he also wants Wayne's girlfriend, a rock singer named Cassandra. Wayne and Garth have to battle the executive not only to save their show, but also Cassandra.

A message from Jim Morrison in a dream prompts cable access TV stars Wayne and Garth to put on a rock concert, "Waynestock," with Aerosmith as headliners. But amid the preparations, Wayne frets that a record producer is putting the moves on his girlfriend, Cassandra, while Garth handles the advances of mega-babe Honey Hornée.
