After being betrayed by her fiance Jason and best friend Bella and left to die outside her own shelter during a frozen apocalypse, Chloe is reborn thirty days before the disaster. Bound to a survival system and a time-frozen storage space, she liquidates assets, stockpiles supplies, and builds an S-class safe house. When the freeze hits, her betrayers become desperate survivors who keep misreading her strength, while Chloe protects her ark through resources, defenses, and ruthless survival choices as a new infection emerges inside the North Sector Base.
