The small, hairy Sumatran rhino is one of the most endangered species in the world. Max has a rare and unique opportunity to join SOS Rhino deep in the jungles of Borneo on a search to find this remarkable mammal. With less than 300 individuals left in the world this is one of Max’s most pressing quests. Luckily his guide, Dr Thaya, knows this animal intimately and has been working in the area for 7 years. Max joins him at his remote jungle camp and together they brave the harsh conditions to search for the rhino, encountering wild orangutan and contending with giant insects, leeches and torrential rainstorms along the way, on what proves to be the most intrepid quest in the series.
