"A woman has been lost in the jungle. She is rescued by natives, stripped naked and chained to a cave. It seems the native religion requires a foreign woman live chained to this cave as an oracle. She is chained mutiple ways: wrists, neck, ankles, waist. Chains lead out of the cave to the rock face but are long enough she can retreat into the cave. The natives provide her with food and water and pull her out by the chains when they need a prophecy.
Surprisingly, something in the cave (hallucinagenic mushrooms? underground gas?) gives her prophetic powers and she begins to fulfil her role with a sense of purpose. The chains become her badge of office and her erotic jewelry. She has become a white goddess ruling a vast jungle realm from her grotto of bondage. She will remain chained to this rock for the rest of her life - and she enjoys the prospect."
