 The Lost Idol of Watusi, a valuable archeological treasure, has come into the hands of Bomba (Johnny Sheffield). Murderous Arabian chieftain Ali Ben Mamoud (Paul Gulifoye) hires the equally unscrupulous soldier of fortune Joe Hawkins (Lane Bradford) to get the treasure. British museum scientist Karen Marsh (Anne Kimbell), Commissioner Barnes (Leonard Mudie), his number one boy Eli (Smoki Whitfield) and Ezekiel (James Adamson) are also seeking the Idol. Hawkins and his native henchman, Gomo (Roy Glenn), double-cross Mamoud and set out to get the treasure for themselves. Things go downhill for them after Bomba takes an active hand; he overpowers Hawkins in an underwater fight and Mamoud is drowned in the coils of a huge water snake. District policemen Reed (William Tannen) and Graves (Don Harvey) place the surviving plotters under arrest, and Bomba and his chimp Kimbbo fade away in the jungle as Barnes, Karen and Eli disappear by boat over the waters of Pongola Basin (played by Monogram s back lot).
