Trapped in a noose rigged by the unscrupulous Werper (Al Ferguson), Tarzan (Frank Merrill) is awarded another blow to his head. After literally throwing Werper and his henchman out the door of his childhood home, our hero, who still suffers from partial amnesia, tries to remember where he had first encountered Werper. Jane (Natalie Kingston) does her best to refresh his memory, but Tarzan remains rather vague. "Your words bring faint memories -- but they are gone in a flash," he admits. Returning to Opar, where Tarzan hopes to remember past glories, the couple is about to be attacked by a ferocious lion.
