While similar in plot to âThe Wizard of Ozâ, The Wiz (usually) uses an all-black cast to transform the show into a more fun, funky modern version. Dorothy, the little girl from Kansas is blown by a tornado into Munchkinland in the Land Of Oz. While there she meets the Scarecrow, the Tinman & the Cowardly Lion on the Yellow Brick Road. She defeats the evil witch and goes to see the powerful Wizard who turns out to be a phoney. However, he is able to convince Dorothy that she can do anything she wants if she just believes in herself. Dorothy also realizes the importance of home and her family.
