In the year 3089, humanity enjoys advanced technology and has established contact with the Karomingians, an alien race initially perceived as friendly. However, a group of Karomingian scientists traveled to Earth's past and downloaded the brain information of Adolf Hitler. This "Brain" then took control of the Karomingian civilization's central system, transforming their political structure into Fascism. Now, these Karomingian Nazis are driven by a single goal: the complete extermination of humankind to establish a world populated only by their own race.
