One Shot’s prime directive is to protect this human child. Together, they form a uniquely endearing alliance. One Shot mentors Amy, but after several years amidst the demolished city ruins, the slightly older girl wants to see the world. And she’s the boss. One Shot and Amy embark on a solitary journey through a devastated world. Immediately, they sense danger tailing them. Robotic mutations they call wolfhounds are tracking Amy to destroy her. One Shot’s sole directive is to keep her safe. When they find other humans, this may become impossible.
