After global warming destroyed the Earth, humanity set off for the uncharted planet paradise known as "Arcadia." Crew member Yeongsu Dong wakes up from stasis to find himself the lone survivor, orbitting the planet in the debris field of the wrecked ship. He gets to the surface, where he is immediately attacked by wild creatures, and gets caught in the civil war among the native Arcadians. He must learn to communicate and survive in this strange new world, and find a way to stop an apocalyptic comet set to destroy his new home.
