First Contact
In the centre of New Guinea there were a million people who believed that they were the only humans on the face of the earth. When the first white men appeared in their hidden valley in the 1930s, they were thought to be the spirits of dead ancestors. The final proof that they were living men came when it was discovered that they had sexual organs and that their excreta smelled like that of everyone else. This is the story of that first contact. The white visitors, who were seeking gold, took with them a film camera and recorded their own exploits and their meeting with the stone-age people. A film unit has been back and talked with some of the men and women seen in the original film.
