Long before Dorothy flew in, two other girls meet in the Land of Oz. Elphaba, born with green skin, is smart, strong-willed and misunderstood. Meanwhile, her college roommate Glinda is beautiful, ambitious and loved by all. However, this Oz is not so pleasant. The Wizard's secret police are everywhere harassing Oz's citizens - especially the animals (which have been threatened with exile). Elphaba, green and misunderstood, is determined to protect the Animals -- even if it means fighting against the imposing Wizard and risking her one chance at romance. In the end, out of guilt and sorrow, she turns into the now infamous "wicked" witch.
