Bindi is travelling deep into the jungles of Borneo to film the plight of orphaned and rescued orangutans. When she gets there, one orangutan captures Bindi's heart: Merah. He's a real scene-stealer! But when a tropical storm hits, Merah escapes from his river island. With poachers lurking nearby, it's up to Bindi and her new friend Siti to track Merah down before the poachers do.
