Rich heiress Aurora gets drunk by her best friend Sabrina and senior Marcus on her birthday yacht trip, who attempt to assault her. A storm capsizes the boat, stranding them on an island. Aurora feigns amnesia after overhearing their plot. When Marcus attacks her in a cave, native youth Kael hears her screams and saves her. Later, Kael subdues Marcus following tribal rituals after another assault. They communicate through gestures and she is accepted by his tribe. A bracelet makes her falsely suspect Kael killed Sabrina, until he shows her the girl’s blood-stained shirt. When rescuers arrive, Aurora invites Kael to leave with her, yet he chooses his homeland. They stare at each other across the sea as the ship departs.
