Plot Elements

 * Humanity, warned of its impending destruction in the crossfire between two warring alien races, constructs interstellar arks to escape Earth. However, only a few arks escape the destruction, including the White Whale ark.
 * Two years after launching, the White Whale is attacked and transported to Mira.
 * During the crash-landing, the Lifehold—a device containing the majority of the human colonists—is separated from the White Whale, with lifepods containing colonists being scattered across Mira. Cross is awoken from a lifepod by Elma and brought back to New Los Angeles.
 * While suffering from amnesia, Cross joins BLADE, working with Elma and Lin to recover more lifepods and search for the Lifehold.
 * During their missions across Mira, BLADE encounters multiple alien races, learning that those attacking them are part of the Ganglion coalition, an alliance of races led by the Ganglion race, who are intent on destroying humanity.
 * During one mission, Cross is wounded, revealing that they are in a robot body. All the people of NLA are in robot bodies called Mimeosomes, with their true bodies held within the Lifehold. The White Whale's power supply is depleting without the Lifehold, meaning the Mimeosomes will eventually shut down, killing the human population.
 * BLADE fight off multiple attempts to destroy the White Whale and the Lifehold, eventually dissolving the alliance between the Ganglion and their allies.
 * Due to his bitterness against NLA's leaders for abandoning his family on Earth, Lao attempts to betray the White Whale to the Ganglion, but is persuaded otherwise and gives them the information needed to find the Lifehold. Other missions also reveal that humanity are descended from the Samaarians, an other-dimensional alien race who once controlled the Ganglion.
 * Within the Lifehold, BLADE discovers a pool of genetic material for recreating Earth's lifeforms and restoring humanity.
 * Elma explains that their human bodies were destroyed with Earth, but their memories and consciousnesses are preserved in the Lifehold's computers for transfer into newly created bodies. Due to the plan's questionable ethics, this decision was kept secret from the general population.
 * Luxaar attacks the group, but Lao fatally stabs him. The two fall into the pool of genetic material causing Luxxar and Lao to merge.
 * BLADE is reluctantly forced to kill them. Before dying, Lao reveals from Luxaar's memories that humanity's DNA was designed by their Samaarian ancestors to destroy the Ganglion using a genetic failsafe. Though Lao dies, Elma assures the group that the Lifehold can revive him.
 * With the Lifehold power restored, Elma deactivates her Mimeosome and reveals her true form as an alien. A narration by Lin reveals that Elma visited Earth thirty years before the Ganglion arrived, giving humanity their means of escape.
 * Mid-Credits Scene: On the White Whale, the crew suddenly disintegrates into golden dust particles, leaving Cross as the only survivor.
 * Post-Credits Scene: A team led by Elma discover that the Lifehold's databases containing humanity's memories were destroyed upon impact with Mira. Elma speculates that Mira is somehow preserving humanity. Lao is then seen unconscious on a beach, waking when approached by a cloaked figure.
