A beautiful, pure-hearted young woman, Maleficent has an idyllic life growing up in a peaceable forest kingdom, until one day when an invading army threatens the harmony of the land. Maleficent rises to be the land's fiercest protector, but she ultimately suffers a ruthless betrayal - an act that begins to turn her pure heart to stone. Bent on revenge, Maleficent faces a battle with the invading king's successor and, as a result, places a curse upon his newborn infant Aurora. As the child grows, Maleficent realizes that Aurora holds the key to peace in the kingdom - and perhaps to Maleficent's true happiness as well.
