You and your parents were shipwrecked on a jungle like island 20 years ago. Your parents were killed by crocodiles when you were 2, but you were taken in by chimpanzees and were taught to climb in trees. You don't remember anything about your human parents or why you're different compared to the other chimps. You're 22 now. One day, a British explorer and his dad, another explorer, set up camp in your jungle. You look on from the trees with interest as you've never seen humans like you before.
