A film drama set against civil war in Peru. When Ortiz, a professional grave robber, stumbles across the huge golden disc of the ancient sun god Atahualpa lost for years, he sets off for Lima where he hopes to sell it for a high price. Chained to the shield, he looks like a giant firebeetle as he crosses the dramatic mountains in Peru pursued by characters with a special interest in the shield. Spurred on by greed, Ortiz's fate becomes inextricably linked to that of the sun god.
