In 2059, five decades after the Space War I conflict seen in the first Macross story. Macross Frontier, the 25th New Macross Class super-long-distance colonization fleet, is journeying through the galaxy to a new paradise to call home. However, it is locked in a state of war with a strange enemy called Vajra. Macross FB7 is the 30th anniversary work of the Macross franchise.

This sequel to the Silent Mobius The Movie 1 continues the timeline of the flashback section of the first movie (Katsumis initial contact with AMP), using some more ideas and persons from the Manga, and being slightly less incompatible to the Silent Mobius series from 1998.

A door opens, and a golden seal shatters a star.

It is the early 21st century. Mankind has lost the battle for planet Earth to Godzilla, and has taken to the stars in search of a new home. But the search ends in vain, forcing them and their alien allies back to Earth. But 20,000 years have passed in their absence, and the Earth is a wholly different place.

The planet's flora and fauna now embody and serve Godzilla. Earth is a monster's planet, ruled by the largest Godzilla ever at 300 meters in height. Godzilla Earth.

Human protagonist, Captain Haruo, yearns to defeat Godzilla and retake the planet for mankind. There, he meets aboriginal descendants of the human race, the Houtua tribe. The Houtua twin sisters, Maina and Miana, lead him to the skeletal remains of Mecha-Godzilla, an old anti-Godzilla weapon, which to everyone's surprise is still alive in the form of self-generating nanometal. Taken from the Mecha-Godzilla carcass, the nanometals have gradually been rebuilding a "Mecha-Godzilla City," a potential weapon capable of destroying Godzilla Earth.

As the strategy develops, a rift forms between the humans and the Bilusaludo, one of several alien races that had joined the humans on their exodus from Earth. Their leader, Galu-gu, believes that the secret to defeating Godzilla lies in the use of superhuman powers – namely, the nanometal integration – but Haruo resists, fearing that in defeating monsters, they must not become monsters themselves. Haruo ultimately uses his means for defeating Godzilla Earth to destroy the Mecha-Godzilla city so as to prevent nanometal assimilation, killing Galu-gu. However, his childhood friend, Yuuko, has been absorbed by the nanometal integration and has fallen into a brain dead coma.

The human race, once again, is lost. Metphies, commander of the priestly alien race, Exif, marvels at the miraculous survival of Haruo, he begins to attract a following. The Exif has secretly harbored this outcome as their "ultimate goal." Miana and Maina issue warnings against Metphies, while Haruo begins to question mankind's next move.

With no means for defeating Godzilla Earth, mankind watches as King Ghidorah, clad in a golden light, descends on the planet. The earth shakes once again with as war moves to a higher dimension.

What is Godzilla exactly? Does mankind stand a chance? Is there a future vision in Haruo's eyes? Find out in the finale.

One day, when Remu Mikage is on a video call with his sister, Shiki, who has traveled to the futuristic Okinotori-island Mega Float City for school, she confesses that both the audio and visuals of her are completely artificial. In order to be more efficient in her studies, Shiki has used neural-linked nanomachines to upload her consciousness onto a computer and is storing her physical body in a "body pool." While shocked, Remu is supportive of his sister's decision, until the disaster known as the "Early Rapture" happens. The Early Rapture causes everyone who has uploaded their consciousnesses to either fall into a coma or perish. Remu visits his sister's empty apartment one last time, but is shocked when Shiki arrives at the door. With no memory of her family or past, and being pursued by a violent group of researchers, Shiki and her brother are forced to flee using her newfound power of nanomachine manipulation.
