Just follow the yellow rock road.

20th Century Oz

Teenage groupie Dorothy rides with a small-time rock band when, suddenly, the van runs off the road, and she hits her head. She awakes in a fantasy world as gritty and realistic as her own and learns that her arrival killed a young thug. A gay clothier, Glyn the Good Fairy, gifts her a pair of red heels as a reward to help her see the last concert of the Wizard, an androgynous glam rocker. As she's pursued by the late thug's lecherous brother, she befriends a brainless surfer, a heartless mechanic, and a cowardly biker.
