A young, powerful fairy named Maleficent lives a peaceful life in the magical moors, a land inhabited by fantastical creatures hidden from the human kingdom. Her tranquil existence takes a dark turn when she falls in love with Stefan, a human boy who betrays her in his ruthless pursuit of power. As King Henry seeks to conquer the moors, Stefan's betrayal cuts deep, leading Maleficent to a path of fury and vengeance. Her heart hardens, and she becomes the realm's fiercest protector, cursing King Stefan's newborn daughter, Aurora, in revenge.

Years pass, and the curse hangs over Aurora's head as she grows under the watchful eye of three inept fairy guardians. Despite her initial resentment, Maleficent begins to develop an unexpected bond with the young princess, who represents not only the innocence of the lands she once loved but also a chance at redemption for the hardened fairy. As the curse's fulfillment nears, Maleficent faces a profound dilemma, torn between her desire for vengeance and the realization that Aurora may hold the key to peace between the kingdoms.
