In a world run by machines, humans are an endangered species.
The Great War is over. The robots have won. The humans who survived have two choices: they can submit and serve the vicious rulers they created, or be banished to the Reserve - a desolate and hopeless slum camp.
Now, following the orders of their soulless leader, the robots are planning to finish what the Great War started and conquer humanity's last refuge.
Six, whose family was killed with the first shots of the war, is a young woman with nothing left to lose. Escaping the Reserve with her friend Dubs, Six knows she must find a way to stop the robots, before they wipe humans off the face of the earth.
