The film was shot on the MGM backlot in Los Angeles, and ignores the plot of the 1931 film about the discovery of a white jungle queen. The new story is written to use stock footage from King Solomon's Mines (1950), and Mogambo (1953). Rod Taylor felt, with the end of the Vietnam War, the time was right for old fashioned hero movies to make a come back.
During World War I, Alfred Aloysius "Trader" Horn leads an expedition in search of a platinum mine in an unexplored region of Africa. The trio encounter warring natives, rhinos and lions. They travel through jungle, swamps, and desert. They are pursued by German soldiers wanting the platinum for the war effort. And by a British officer hunting Horn as a traitor.
