Plot
Te Fiti, an island goddess, created all life and became an island after falling into deep slumber. Te Fiti's heart, a small pounamu stone, was sought after by the monstrous forces of the sea, until it was stolen by the demigod Maui.
Leaving the island without the heart caused it to collapse and a lava monster named Te Kā to appear and confront Maui, which caused his fish hook and the heart to disappear into the ocean. Because of the heart being stolen, the islands Te Fiti created are cursed to lose the life she gave them.
A millennium later, Moana as a toddler discovers the heart as she is collecting shells near the ocean. After her chieftain father Tui orders her to return to the village, she never sees it until she has grown up. Moana, now a teenager, has the responsibility of becoming the next chief of the island as her father insists, but due to her close friendship with her grandmother, Gramma Tala, she keeps her dream of leaving the island alive. 
She soon discovers that all the fish have disappeared from the shores of the village, and the coconuts have spoiled. Moana insists on going beyond the reef to catch more, but her father dismisses her request, angered by her wishes. Her mother Sina confesses that her father acts like this because of the loss of his closest friend when they went sailing to unforgiving waters one night in his youth.
Gramma Tala finds Moana on the beach after she tries to sail past the reef only to become shipwrecked back home and shows Moana a secret cave hidden behind a waterfall. Inside are the sailboats that her ancestors stowed away. By banging the drum, she discovers they were voyagers.
Tala then gives Moana the heart of Te Fiti after showing her the curse of draining life away from trees and the island itself, saying that it is the only way to save her people. She goes to her father and tells him what Tala told her, but he doesn't listen and sees it as another excuse for her to leave the island.
Later, Tala is seen ill and is found dying on her deathbed. With her dying breath, she tells Moana to go save her people and gives her the necklace used to carry the heart. Moana departs using one of the sailboats found in the cave and departs with Heihei, a dumb rooster who has accidentally stowed away on the sailboat.
She seeks to find Maui by following a constellation that looks like his fish hook, but a wave flips her sailboat and knocks her unconscious. She wakes up the next morning on a small island inhabited by Maui, who traps Moana in a cave after distracting her with a tune. He steals her sailboat while threatening to eat Heihei.
After escaping the cave, the ocean sends Moana back on the sailboat to convince Maui. She shows him the heart and asks him to help her return it, but Maui backs away fearing that the heart is a trap for the person carrying it and that other creatures would kill to steal it for themselves.
