Based on Gregory Maguire's novel, which turned every Oz myth inside out, Wicked explores the early life of the witches of Oz: Glinda and Elphaba. The two main characters meet at Shiz, a school where both hope to take up sorcery. Glinda is madly popular and Elphaba is, well, green. By a misunderstanding, they wind up roommates and, after an initial period of mutual loathing, begin to learn something about each other. Their life paths continue to intersect through a shared love, entry into the Emerald City and interaction with the Wizard himself. Eventually, their choices and convictions take them on widely different paths.
