At Liberia's only home for rescued chimpanzees, there are more new arrivals. Jimmy and Jenny Desmond and their team now have 28 chimps to look after, including an eight-week-old baby called Gaia. Plans come together for the new sanctuary in the forest, and the orphans learn to master tools so they can forage for food. But a deadly cold breaks out among the babies, with disastrous consequences. And the team rescues an adult male chimp called Jonny who brings a new set of challenges. The pressure is on to move the chimps to their new home, before things get out of hand.
