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. She rises to be the land's fiercest protector, but she ultimately suffers a ruthless betrayal – an act that begins to turn her heart into stone. Bent on revenge, Maleficent faces an epic 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 to Maleficent's true happiness as well.

Maleficent and her goddaughter Aurora begin to question the complex family ties that bind them as they are pulled in different directions by impending nuptials, unexpected allies, and dark new forces at play.
