After Earth is taken over by an army of robots, the small number of humans left are forced into hiding. In the nuclear winter, only droids walk the face of the Earth, in fear of the rumored human resurgence, and in search of a hidden cache of weapons. One robot, his evil circuits destroyed, enters a small town where a robot civil war is taking place. He tries to convince both sides to join forces in search of the weapons, all the while having a hidden agenda, and an affinity for one of the local droids.
