In Rust City, which is shrouded by the "God's Eye" orbital defense system, any first-level object moving faster than ten meters per second will be instantly vaporized. The mercenary Crow Que has an extremely rare "time sense" and can capture the 0.5 Second "blink" gap of the system once every minute. In order to save his sister who was suffering from rust lung disease, he accepted an almost fatal mission: transporting a heart that must keep beating at "supersonic speed" in a world with speed limits.
