When the pressure to be royal becomes too much for Mal, she returns to the Isle of the Lost where her archenemy Uma, Ursula's daughter, has taken her spot as self-proclaimed queen.

A beautiful princess born in a faraway kingdom is destined by a terrible curse to prick her finger on the spindle of a spinning wheel and fall into a deep sleep that can only be awakened by true love's first kiss. Determined to protect her, her parents ask three fairies to raise her in hiding. But the evil Maleficent is just as determined to seal the princess's fate.
