Overview: Sheena and Bob must rush to help save the life of Dr Mitchell Heller (below left) whose life is in danger from Eddie Lewis, a treacherous safari guide (below centre). Sylvia, Heller's daughter (right), tells them that her father is attempting to reach the Temple of the Elders because he has become obsessed with finding a drug to prolong life. She also says Lewis stands to collect a large amount of money, even if Heller dies during the expedition. Sheena protects Heller from Lewis but Lewis forces her to lead them to the temple by threatening to shoot Chim. Sheena leaves a trail for Bob to follow but when they reach the temple Sheena, Lewis and Heller are all taken captive. The 300-year-old Ancient One condemns them to imbibe the youth potion which is a deadly poison to anyone who has not taken it daily since childhood. Bob arrives and points out Heller is a good man with an unhealthy obsession and that Lewis forced Sheena to guide them to the temple. Lewis grabs Bob's rifle, steals the Ancient One's potion but he is killed by a guard's spear. Heller realises that the value of life lies in it's quality and is reunited with Sylvia.
