In the machine-controlled city of Sistepolis, M225, a dissatisfied young programmer, is rescued during her commute to work by Niko, an ally of the resistance. Together, they escape to Geapolis, a free world where Gea, the leader of the resistance, guides them. Gea seeks the valuable assistance of M225 to overthrow Sistepolis and liberate its people. Now, M225 becomes the last hope to challenge the dominion of the machines and restore freedom in both worlds.
