The world has apparently been destroyed in a great war in the 1980s, and a survivor (William Lanning) lives on a remote island with just snakes and a mainframe with all of humanity's knowledge for company. He narrates the film, recounting the events that led up to the present.
These involve a nefarious Nazi plot to revive the Third Reich with clones of world leaders. Robert Vaughn is a secret agent sent to uncover the plot and defeat the Nazis, who in most cases are the most laughable examples ever.
The film has problems, the main being the way the story is driven by the narrator which just lacks any energy or suspense. Action scenes cut to yet another shot of the narrator looking bored at a monitor. The film also takes quite an age to get going. It's not all bad, as a campy bit of sci-fi neo-nazi evil plan cinema it is quite passable.
