In the last episode of this innovative landmark series combining human drama, natural history and computer graphics, the BBC Natural History Unit recreates the lost world of New Zealand. When the Maori first discovered New Zealand 850 years ago, they ventured into the unknown. A weird landscape inhabited by an extraordinary and exotic group of animals and plants. A land patrolled by the largest bird ever to walk the earth and the deadliest aerial predator since the time of the dinosaurs. For the Maori, it was like a Hitchcock horror - a land ruled by birds. This film tells the story of the Maoris' courageous endeavours to survive in an alien land. It is a story that gives insight into human nature. A film that delivers a stark warning to us all.
