Fu Manchu's 168th birthday celebration is dampened when a hapless flunky spills Fu's age-regressing elixir vitae. Fu sends his lackeys to round up ingredients for a new batch of elixir, starting with the Star of Leningrad diamond, nabbed from a Soviet exhibition in Washington. The FBI sends agents Capone and Williams to England to confer with Nayland Smith, an expert on Fu.

A group of covert CIA operatives trailing a potential new energy source are double-crossed by corrupt agent Morgan, who causes a helicopter crash in remote South Africa. The sole survivor, suffering severe amnesia, is nursed to recovery by a kindly native tribe who call him "Whoami" after the question he keeps asking. With the help of a mysterious reporter Christine, Whoami pieces together his past and tracks the turncoat agent and his criminal cohorts.
