Background: In the near future, the melting of glaciers will trigger a global flood. Half of the coastal cities will be submerged. Humanity will retreat to the inland highlands to build "Ark City". At the same time, the ancient creatures sleeping in the deep sea awakened, represented by the white giant Qi Shi, who regarded human beings as the culprits of destroying the marine ecology, and attempted to completely destroy human civilization through floods. Qi Shi turned into a human and lurked in Ark City, using floods and mutated creatures to create chaos.
Intention: Prejudice and understanding between species, contradiction between individual emotions and group mission.
