Competing expeditions attempt to locate a buried treasure of ivory tusks in this highly politically incorrect (by modern standards) Universal serial released in 12 chapters and starring Tom Tyler. The lanky actor convincingly exchanged his usual Stetson for a pith helmet to play big-game hunter Kirk Montgomery, who is not only searching for the ivory, but also a young boy lost in the jungle. The boy's sister (Cecilia Parker) and father (William Desmond) constitute the Morgan expedition, which is constantly waylaid by the competitor, a gang of roughnecks led by villainous Philo McCullough. There is a femme fatale (Carmelita Geraghty) and a strange ape-like creature for added excitement, but good conquers evil in the final chapter, "Buried Treasure." ~ Hans J. Wollstein, Rovi
