This is the story of a people who came into a pristine environment only some 15 centuries ago. With the island’s very limited resources this society achieved astonishing feats, but put enormous demands on their environment.

Two "Ancestor-Spirits" glide along the centuries, witnessing the harrowing tale, up to the peaceful present.
