Set 9 years after the fall of an alien spaceship on Earth and one year before Space War 1, the first large-scale extraterrestrial war. The alien ship, which would later be rebuilt and rechristened SDF-1 Macross, caused the formation of a U.N. government and helped trigger the U.N. wars. Amidst the violence, a U.N. F-14 pilot named Shin Kudo is attacked by strange enemy aircraft that can transform into robots.
