20th Century Oz (1976)

Dorothy is a 16-year-old groupie riding with an up-and-coming rock band when, suddenly, their van is in a road accident, and she hits her head. She wakes up in an alternate reality that's as gritty and realistic as the one she came from, and learns that she killed a young thug with the van. A gay clothier called the Glynn the Good Fairy gives her a pair of red shoes as a reward to help her see the last concert of the Wizard, an androgynous rock singer, in the city (Melbourne) that evening. She is pursed by the thug's brother who attempts to rape her on several occasions. During her journey, she becomes the traveling companion of a dumb surfer, a heartless mechanic, and a tough biker.
