Cold storage quality inspector Mia Winters has lost both parents and is raising her high school student brother Leo alone. On the seventh day of the countdown to the apocalypse, she broke up with her boyfriend Derek Moore and her best friend Vanessa Blake in a hotel - they conspired to swallow up the warehouse and savings left by her father, kicked her out of the house, and left her with nothing. On a night of despair, the 'Extreme Cold Apocalypse Survival System' awakens: in seven days, global temperatures will plummet to minus 60 degrees Celsius. She suppressed her humiliation and spent seven days frantically hoarding goods, unlocking her spatial abilities layer by layer - not only can she preserve and hoard, but she can also store "heat" and freeze "time". As the apocalypse arrived, she walked out of the house with a space filled with supplies and bumped into a shivering scumbag who came to seek help. Afterwards, she survived while slapping her face, and traced the confidential drawings of the Glacier Group in her father's belongings, discovering a shocking conspiracy of man-made disasters hidden behind the extreme cold disaster.
