The final episode of the series kicks off in style as Luke hits the streets of Kampala in order to catch a disheveled dog. Conservation is then the order of the day as Luke sets off to see some of the world's most endangered animals. He helps treat a couple of chimpanzees at a sanctuary on Ngamba Island, where he also follows the rehabilitation of two young and very cheeky chimps. He tracks down some white rhinos that have been released back into the wild after a twenty-five year absence and after a long drive into the dense countryside he spends an even longer day helping a community of farmers with all their livestock. The adventure ends as Luke fulfills a boyhood dream: heading into Bwindi Impenetrable Forest to track down one of the world's most mystifying creatures, the mountain gorilla.
