Gordon Mitchell heads the cast in this campy sci-fi tale directed by Umberto Scarpelli. It seems that insane King Yotar (Roldano Lupi), obsessed with technological advancement and the secret of immortality, has inflicted inhumanities upon his subjects: the people of Atlantis. Enter muscleman Obro (Mitchell) to stop the sovereign and his minions from manipulating the laws of nature and destroying the world -- but is it too late?
