In 1999, an alien ship crashes on South Atalia Island and makes the human race aware of other life in space. Ten years later, the ship is reconstructed and christened as the SDF-1 Macross. However, on the day of its maiden voyage, an alien race called the Zentraedi make their appearance on Earth, beginning the UN Spacy/Zentraedi war that would change the history of both races forever.
