Picking up quite a while after the defeat of Clayton, Jane and Professor Porter now speak Gorilla-language fluently and Jane is married to Tarzan. However, their lives are threatened once again by a brutal band of British explorers led by the unscrupulous Oswald Gardner, who becomes fascinated with Tarzan and strives to capture the ape-man and take him back to England as a media attraction.
