Astroboy and Dr Elefun, venture to South America with Dr Gustav Usurper. They're investigating reports of strange lights around the Incan ruins. When Astro breaks off from the group, Elefun and Usurper blunder into an Incan tomb. There they meet Keepu, last of a long line of Incan priests. He has mastered 'telekinesis' and plans to use his powers to recover the Incan artifacts which have been plundered over the centuries.
