When a bacteria strain decimates humanity, an A.I. equipped biotech virus is unleashed to combat the plague. But scientists soon discover that the "nanos" are adapting, taking over their hosts, and spreading rapidly.
Against this apocalyptic backdrop, masked swordsmen, government agents, scientists, and soldiers fight to cleanse the earth of the infected. Some form symbiotic relationships with the "nanos" to become superhuman, while others devolve into monsters.
As the infection grows, hope is kindled in a rumored "Lost Owl Kingdom," a community of rural doomsday preppers. With a strict code and advanced training, the survivors rally under the banner of the OWL, a beacon of wisdom and salvation for mankind.
