Akronos has discovered the Geometric Nucleus during the course of his research. The Nucleus is a device of incredible power that could be used as a terrible weapon in the wrong hands. Akronos feels that the Nucleus must be kept from evil men at all costs. When he learns that the evil Zor and his army are approaching his castle, he asks his daughter Mila to bring his former student Ator back to help defeat him. Mila runs away to find Ator. Zor's soldiers enter and begin beating Akronos, but Zor angrily sends them away to maintain his magnanimous image. Mila is pursued by Zor's soldiers and is wounded by them but continues to stagger towards Ator's home. At last, she arrives, and Ator uses his medical knowledge to heal her wound. She is then able to convince him that she is the daughter of Akronos, and that her father is in terrible danger. Mila, Ator, and Oriental warrior Thong begin the journey back to Akronos' castle, facing various dangers along the way, including a tribe of cave-dwelling cannibals, another group determined to sacrifice them to their god (which is a giant snake), and other soldiers. Finally, they make it back to the castle. While Mila and Thong sneak in the back way, Ator uses his knowledge of flight to quickly create a
hang glider, which he flies over the castle, dropping bombs on Zor's soldiers. Having defeated most of Zor's forces, Ator takes on Zor himself and defeats him. Akronos convinces Ator to let Zor live to face trial, but when Ator steps away, Zor grabs a sword to threaten Ator, and Zor is killed by Thong. Afterward, Akronos gives the Geometric Nucleus to Ator. Ator tells Mila he has to leave, that his life is too dangerous to share with her. Mila says that she knows Ator must fight evil where ever it occurs. Ator leaves Thong behind to help take care of Mila and Akronos. He then takes the Nucleus to a distant land, where he destroys it, resulting in a nuclear explosion. ==Cast==
