As opening titles on black fade, we rise out of a river. On the shore are members a tribe of Early Humans. They are digging tubers, weaving, and butchering a carcass. A leaf-armored sentry nearby is leaning on a stick. In the distance, smoke is rising from a little village.
Suddenly, an ornately costumed Stranger steps from the bush. The villagers howl in alarm as the Stranger stares at them, then slowly holds up a long, mysterious object – could it be a weapon? The sentry, suddenly leaps from a bush and a battle ensues.
Meanwhile, in the distance, a stilt-walking Land Raft appears, walking above the treetops. It is being “rowed” by a whole tribe of Strangers!
Everyone on the river bank runs for shelter, except for the Stranger, who holds up the long object again. He raises it to his mouth and plays a hypnotic song. He is answered by another who stands at the prow of the Land Raft, playing a similar instrument.
Meanwhile, an old woman of the village has collected offerings in a basket. She crosses the stream and it near the Stranger, who stops playing, looks at her, then removes the long, birdlike mask, revealing a Neanderthal face underneath. We sink into the water again as the scene fades to black. End Titles.
