In 2009, humanity finds itself under siege by a race of giant, warlike aliens called the Zentradi. During their initial attack, the SDF-1 Macross—a transforming space fortress housing thousands of civilians in addition to military personnel—is flung to the far side of the solar system due to a faulty space fold. Struggling to make it back to Earth with the enemy forces hot on their heels, the morale of the people on board is bolstered by the singing of superstar pop idol, Lynn Minmay. Fighter pilot Hikaru is one of her biggest fans, and a daring rescue leads to a potential romance between the two. But the Zentradi also have their eyes on Minmay, as her love songs stir up ancient memories of what may be their only weakness: Proto-Culture.
