The Earth has descended into a new ice age of -45 degrees Celsius. At the evacuation center, dozens of people who have fled are living on the edge of their lives. In a world where civilization has collapsed, money and status have no meaning and every blanket and canned food is sought after, values have changed drastically. Humanity is faced with an extreme situation where only those with a strong desire to live will survive.
Kimura Shoko, a genius con artist with two previous criminal convictions, is determined to do whatever it takes to survive in this new world. For some reason, the shelter she arrives at values family over everything. As the “mother” of a “masquerade family”, she faces harsh days. Behind Shoko’s explosive desire to survive is a desire to see her son again.
