<P> While Dorothy cleans up after the meal, Dorothy's dog Toto runs out the open kitchen door into a violent snowstorm . She succeeds in retrieving him, but finds herself trapped in the storm . A magical whirlwind made of snow--the work of Glinda, the Good Witch of the South (Lena Horne)--materializes and transports them to the realm of Oz . Released by the snowstorm, Dorothy smashes through an electric "Oz" sky sign as she descends from the atmosphere, and which falls upon and kills Evermean, the Wicked Witch of the East who rules Munchkinland . As a result, Dorothy frees the Munchkins who populate the playground into which she lands; they had been transformed by Evermean into graffiti for "tagging" the park walls . </P> <P> Dorothy soon meets the Munchkins' main benefactress, Miss One, the Good Witch of the North (Thelma Carpenter), a magical "numbers runner" who gives Evermean's pretty charmed silver slippers to her by teleporting them on Dorothy's feet . However, Dorothy declares she doesn't want the shoes and desperately just wants to get home to Aunt Em . Miss One urges her to follow the yellow brick road to the capital Emerald City and seek the help of the mysterious "Wizard" who she believes holds the power to send Dorothy back to Harlem . After telling her to never take the silver shoes off, the good witch and the Munchkins then disappear and Dorothy is left to search for the road on her own . </P> <P> The next morning, Dorothy happens upon a Scarecrow (Michael Jackson) made of garbage and rags, and saves him from being viciously teased and picked on by a group of humanoid crows and whom she befriends . The two of them discover the yellow brick road and happily begin to follow it together . The Scarecrow hopes the Wizard might be able to give him the one thing he feels that he lacks--a brain . Along the way to the Emerald City, Dorothy, Toto, and the Scarecrow meet the Tin Man (Nipsey Russell), in an abandoned early 20th - century amusement park and the Cowardly Lion (Ted Ross), a vain dandy banished from the jungle who hid inside one of the stone lions in front of the New York Public Library . The Tin Man and Lion join them on their quest to find the Wizard, hoping to gain a heart and courage, respectively . Before the five adventurers reach the Emerald City, they must face obstacles such as a deadly subway where they meet a crazy subway peddler (a homeless man) who unleashes evil puppets in his control . They narrowly escape the subway and then encounter the "Poppy" Girls (a reference to the poppy field from the original story), flamboyant prostitutes who attempt to put Dorothy, Toto, and the Lion into an eternal sleep with magic poppy perfume . </P> <P> Finally reaching the Emerald City (an analogue of the real - life World Trade Center plaza), the quintet gains passage into the city because of Dorothy's ownership of the silver slippers; they marvel at the spectacle of the city and its sophisticated, fashion forward dancers . They are granted an audience with the Wiz (Richard Pryor), who lives at the very top of the Towers . He appears to them as a giant fire - breathing metallic head . He will only grant their wishes if they kill the sister of the Wicked Witch of the East, Evillene (Mabel King), the Wicked Witch of the West, who runs a sweatshop in the underground sewers of Oz . Before they can reach her domain, Evillene learns of their quest to kill her and sends out the Flying Monkeys (a motorcycle gang) to kidnap them . </P>
