Its 6 weeks since new chimp mum Yao and her baby Miko escaped from the safety of their sanctuary in Mefou National Park. They've been living in the surrounding forest, which is littered with the traps and snares of local villagers who rely on the forest for their food. But when they're finally caught, it all goes wrong for Miko. At the Sanaga Yong Chimpanzee Rescue Centre in the heart of the rain forest, they don't have the luxury of electricity. And that means an hour's drive on rough tracks to the nearest fridge where their medicines can be kept cool. But on a routine trip they arrive to find town closed. Baby gorilla Shufai leaves Rachel forever as he takes the next step on his journey back to the forest.
