There are more new arrivals at the home, meaning Jimmy and Jenny Desmond now have 28 rescued chimpanzees to look after, including an eight-week-old baby called Gaia. Plans are coming 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. The team also rescues an adult male chimp called Jonny who brings a fresh set of challenges. The pressure is on to move the chimps to their new home before things get out of hand.
