Follow Shufai, a baby gorilla who was orphaned by hunters who killed his mother for her meat. He's in desperate need of surgery but for vet Sheri Speede, conditions are basic - an emergency operation takes place on the kitchen table. An ex-gorilla hunter who's killed hundreds of the world's most endangered primates, goes undercover in one of Cameroon's bush meat markets. We also see how the keepers cope with trying to capture 19 escaped chimps back into the safety of their forest enclosure.
