In the forty-seventh year after the nuclear fire, the "Rust Iron Wasteland" is the last tombstone of civilization and the most cruel arena of survival. Radiation dust storms swallow up hope, clean water is more expensive than gold, and the Iron Alliance - the steel behemoth rising in this wasteland - uses high-pressure rule and monopolizes the source of life to keep the remaining humans in fear and despair.
Renn, a lone hunter in the wasteland, only believes in the railgun in his hand and the rules of survival engraved in his bones. The vague barcode on his arm is the mark left by a crazy experiment before the war, and it is also the past that he desperately wants to forget. During an in-depth exploration of the "New Atlanta" shelter, he not only found priceless pre-war data cores, but also attracted the most elite "Hound" scouts of the Iron Alliance. That imprint turned out to be a "genetic mark" that the Alliance was hunting down at all costs.
On the run, Lane is forced to form a fragile alliance with Ellie Wu, a woman whose identity is a mystery and who possesses unusual radiation resistance. Ellie carries a coordinate chip that points to the legendary "Eden" water purification system, which is the only hope to end the Iron Alliance's water purification monopoly and ignite the fire of rebellion in the wasteland. However, the mark of the laboratory is also engraved behind Ellie's ears, and her blood is filled with unknown secrets and a fatal price...
