Thus begin the Unification Wars, a worldwide war that eventually unites the planet under the governance of the United Nations. Now, a decade later, the reconstruction of the crashed alien craft – dubbed "Macross" – is complete. However, on the day of its christening, the Macross unexpectedly fires and destroys several approaching Zentradi spaceships. The last hope of Earth, the Macross, begins to wage a lonely war; but what hopes can one ship have when facing against an entire alien race?
