Don Juan is sent on a quest to find the magical Ibong Adarna bird to cure his ailing father, the King. He succeeds where his two older brothers failed, avoiding their fate of being turned to stone. After many adventures, including rescuing princesses from dangers in an underground world accessed via a deep well, Don Juan continues his journey to find the kingdom of Delos Cristal and the beautiful princess said to be even lovelier than his love interest, Princess Leonora. He seeks information from increasingly older hermits, the latest being 800 years old, who he hopes can provide directions to the elusive kingdom.
