In a ruined, nameless city of the future, a woman named Rachel, who makes her living as a scavenger, finds a small green lump of a creature she names "Borne" entangled in the fur of Mord, a gigantic, despotic bear. Mord once prowled the corridors of the biotech organization known as the Company, which lies at the outskirts of the city, until he was experimented on, grew large, learned to fly and broke free. Driven insane by his torture at the hands of the Company, Mord terrorizes the city.
