In the opener of Universal's 15-chapter serial Tarzan the Tiger, Tarzan, aka Lord Greystoke (Frank Merrill), returns to Africa with his bride, Lady Jane (Natalie Kingston), hoping to locate the famous Jewels of Opar and thus save the Greystoke estate in England. At their plantation, the noble couple is entertaining seemingly friendly scientist Albert Werper (Al Ferguson) who, unbeknownst to the Greystokes, is in reality a greedy soldier of fortune. To Werper, Tarzan explains how he, years ago, rescued Lady Jane from La (Mme. Kithnou), the jealous Queen of Opar. "Have you no pity for me -- a woman like yourself," a tied-up Jane had pleaded, but to no avail. Happily, Tarzan had arrived with not a second to spare to rescue Jane from certain death. Now, and despite Jane's misgivings, the Englishman is planning to return to Opar. Werper, meanwhile, conspires with Tarzan's enemy, slave trader Achmet Zek (Sheldon Lewis), to sell Lady Jane to the highest bidder. The following night, while Tarzan is fighting the ferocious lion Numa, Zek and his band of Nomads kidnap a prostrate Jane.
