Opening Narration: Where are we going? Life, the timeless, mysterious gift, is still evolving. What wonders-or-terrors-does evolution hold in store for us in the next ten thousand year? In a million? In six million? Perhaps the answer lies in this old house in this old and misty valley...
Closing Narration: An experiment too soon, too swift, and yet may we still hope to discover a method by which, in one generation, the whole human race could be rended intelligent, beyond hatred, or revenge, or the desire for power? Is that not after all the ultimate goal of evolution?
Gwyllm Griffiths: The human race has a gift, Professor, a gift that sets it above all the other creatures that abound upon this planet: the gift of thought, of reasoning, of understanding. The highly-developed brain. But the human race has ceased to develop. It struggles for petty comfort and false security; there is no time for thought. Soon there will be no time for reasoning, and Man will lose sight of the truth!
