Darman, his daughter Ida, and Slamet the servant, go into the woods to hunt. Ida was lost when Darman and Slamet are chasing a tiger. Ida ends up in Tarsan's hut. They become close though at first, Tarsan has problems speaking the Indonesian language. Then he agrees to go to the city and learn how to be an urbanite. It is not easy as he is even harassed by Ida’s friends who do not like him.
Taking their being fallen from the sky as the gods' omen, the babies christened as Tar and are declared heir to the chieftainship of the Agatao tribe. The tribe looks forward to Tar and San's succession, for both are amiable and magnanimous to them; but since the chieftain's evil nephew Sabukot also stakes his claim on the throne, the Agatao chieftainship becomes a prize the claimants have to win. Adventuress Jessie and her team enter the scene, declaring Tar and San to be the long-estranged grandsons of rich philanthropist Gerardo Elizondo. Tar and San are taken to the city to learn the ways of the place they are meant to belong, but no matter how hard they try to adapt, the two cannot resist the call of the wild.
