Millions of years ago, the earth was covered with frozen snow. Hence it was known as the Ice Age. George, Brenda and Jack are three friends who have known each other well since childhood. One afternoon, they inadvertently heard loud noises that were inaudible to others. Driven by curiosity, they looked for the source of the noises and found a mysterious ancient book. The phrase “The ancient Earth was covered with snow and ice …” took them to another time space which was extremely cold. They met the guardian of the ancient book, the Water Lord. How do they survive in the extremely cold weather of the Ice Age? How can Water Lord help them get away from the chase by the sabre-toothed tiger and short-faced bear? Can they get home safely?
