Billionaire heiress Chloe is betrayed by her fiancé Liam and stepsister Mia during the frozen apocalypse. After stealing her fortune and safe house, they throw her outside to be devoured by zombies. But Chloe wakes up seven days before the end of the world and unlocks a mysterious necklace left by her mother—an expandable infinite storage space.
This time, she cuts off the traitors, stockpiles massive amounts of food, medicine, and military supplies, and transforms her estate into an impenetrable doomsday fortress. While searching the underground black market for diamonds to expand her space, she rescues Asher, a brutal experimental fighter carrying a mysterious werewolf mutation.
When the apocalypse arrives earlier than expected, the city collapses under extreme cold, zombies, and human greed. While Chloe's enemies freeze and starve outside, she commands unlimited resources from inside her fortress—with Asher, the world's most terrifying biological weapon, standing at her side. Feared by everyone else but fiercely loyal to her alone, Asher becomes both her ultimate protector and her destined mate. Together, they uncover the truth behind the genetic experiments, destroy the forces responsible for Chloe's mother's death, and rewrite the rules of the post-apocalyptic world.
