Gorilla attacks on humans are a surprise to Jungle Jim, as the creatures are not known to exist in this part of
Africa. On his way to see Frank Bentley, warden of the
Nairobi animal preserve, Jim encounters Nyobi, a young woman in distress, and saves her life. Bentley is ill and is being treated by Dr. Brandt, who, unknown to all, is in league with fortune hunters trying to find a trove of hidden Nazi gold. Barbara Bentley, the warden's niece, accompanies Jim and learns that men are wearing animal costumes, disguising themselves as gorillas and lions, to make the deaths appear accidental. Although all three are captured, Jim is able to free Barbara and Nyobi and defeat the culprits. Nyobi, revealing that she is actually a princess, is permitted to take the gold back to her people. ==Cast==
