In 2020, robotics company C.E.O. Elias VanDorne reveals Kronos, the supercomputer he has invented to end all war. Kronos decides that mankind is responsible for all war, and it tries to use robots to kill all humans. VanDorne and Damien Walsh, a colleague, upload themselves into Kronos and watch the destruction. Ninety-seven years later, Andrew, a kind-hearted young man, wakes up in a ruined world. VanDorne and Walsh, still in Kronos, watch Andrew meet Calia, a teenage girl who seeks the last human settlement, the Aurora. Though Calia is first reluctant to let Andrew accompany her, the two later fall in love.
