The world of robot technology has become a dystopian nightmare as robots across the United States begin to attack anyone and everything. Among the chaos, two humanoid bots, Beck and Call, remain functional. Beck, a combat robot and the latest in the Mighty Numbers line, possesses the unique ability to manipulate Xels, the nanomachines that comprise all robots. Dr. White, Beck's creator, asks him to bring his fellow Mighty Numbers back to their senses and uncover the source of the robot affliction.
