The story narrates the vicissitudes of Doctor Oedo's research group (Galax), whose objective is to reach the tenth planet of the solar system, Prometheus, in order to exploit its natural resources and guarantee a future for humanity. However, Prometheus is also in the sights of Doppler, a rich and evil scientist at the head of a paramilitary organization (which resembles the Nazis in terms of uniforms and hierarchy) who has decided to make the tenth planet the homeland of a new race of chosen ones.
