The Storm of Tarzan (1937)

After years of research, Ramu, a brilliant scientist who lives with his wife Uma and their four-year-old son Leher in the jungle, comes up with the nectar of immortality: an innovative formula that can save the lives of millions. Then, tragedy strikes. Fifteen long years later, Ramu's father and his adopted daughter, Leela, arrive in Vanrajpur, a town on the outskirts of the jungle, to search for any trace of his son, daughter-in-law, and grandson, unbeknownst to him that one of his men, Bihari, has sinister ulterior motives. As the team embarks on a peril-laden mission into the impenetrable forest, cannibals attack, catching the attention of an elusive but powerful man. Can the legend of Tarzan, defender of the jungle, be true?
