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.

The show's main protagonist is the 5-year-old title character Chico-chan. An actor wears a costume with an oversize head to portray her, while the broadcasts show her face in 3D computer graphics, which allows for a variety of outrageous expressions and effects. Accompanied by comedian Takashi Okamura, the show features Chico-chan asking Okamura and others simple questions, such as "Why do people wave their hands when they say goodbye?" If they cannot answer properly, she spits out her sarcastic signature phrase, "Botto ikiten ja ne-yo!" (Don't sleep through life!) Yuichi Kimura provides the voice of Chico-chan.
