With the exceptions of Erik Von Detten and Jason Marsden as Flynt and Mungo respectively, none of the actors from the original film reprised their roles.

The picnic is interrupted when two panthers, Nuru and Sheeta, attack Jane and her friends, forcing them to flee into the deeper regions of the jungle.

Back to the present day, Jane ponders over the idea of expensive gifts, particularly jewelry, prompting Terk to remind her of the time Tarzan tried to get her a diamond.

The volcano then erupted with Tarzan, Jane, and Professor Porter trapped inside, though they managed to escape before the lava flows reached them.

Things had gone well, despite Tarzan feeling jealous and mistrusting towards Canler (claiming that he is a bad man who reminds him of Sabor, which Jane dismisses) until Canler revealed he was working as a double agent for the Germans of the German Empire during World War I and had come for a code machine disguised as a music box he gave to Jane for safekeeping.

He then kidnaps her, but was tracked down and stopped by Tarzan assisted by RAF pilot Nigel Taylor, who had been on Canler's trail.
