On the Polynesian island of Motunui, the inhabitants worship the goddess of creation Te Fiti, who brought life to the ocean using a pounamu stone as her heart and the source of her power. Maui, the shape-shifting demigod of the wind and sea and master of sailing, steals the heart to give humanity the power of creation. However, Te Fiti disintegrates, and Maui is attacked by another who seeks the heart: Te Kā, a volcanic demon. He loses both his magical giant fishhook and the heart to the depths of the sea.
