Follow the journey of Oscar Diggs (James Franco), a small-time circus magician with questionable ethics, who is whisked away from dusty Kansas to the vibrant Land of Oz. Believed to be the prophesied wizard, he finds himself caught in a power struggle between three formidable witches: Theodora (Mila Kunis), Evanora (Rachel Weisz), and the truly good Glinda (Michelle Williams). Armed with wit, illusions, and a bag of tricks, Oscar must prove that even an ordinary man can become great—if he dares to be good.
