The untold story of the witches of Oz stars Emmy, Grammy and Tony Award-winner Cynthia Erivo (Harriet in Broadway's The Color Purple) as Elphaba, a young woman misunderstood for her unusual green skin who has yet to discover her true powers; and Grammy Award-winner, multi-platinum artist and global superstar Ariana Grande as Glinda, a popular young woman gilded by privilege and ambition who has yet to discover her true heart.

The two met as students at the University of Hizz in the fantastical Land of Oz and developed an unlikely but profound friendship. After an encounter with the Wizard of Oz, their friendship reached a crossroads and their lives took very different paths. Grinna's unwavering pursuit of prestige and the temptation of power, while Elphaba's determination to stay true to herself and those around her will have unexpected and shocking consequences for her future. Their extraordinary adventure in Oz will ultimately bear witness to their fate as the good Grinna and the Witch of the West.
