Journalist Graham Hancock travels the globe hunting for evidence of mysterious, lost civilizations dating back to the last Ice Age.

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.

Professor Alice Roberts journeys 40,000 years back in time on the trail of the great beasts of the Ice Age. This was the last time that giants like mammoths, woolly rhinos, and sabre-tooth cats ruled the Earth and Alice attempts to reconstruct their lives in incredible detail.

Biologist Liz Bonnin and geologist Martin Pepper set out on a global expedition to answer the most thought-provoking questions in earth science today. Throughout history, such geologic events as volcanic eruptions, tsunamis, tectonic plate motion, earthquakes, and asteroid impacts have continually reshaped Earth's surface, spreading chaos across the planet. By performing experiments, making observations in the field, and consulting expert scientists, the eight-part series works to uncover Earth's immeasurable capacity to create and destroy.
