Liz and Sophie decide to go to the Arctic in Northern Europe and North America to take polar photographs after seeing a picture of an Icelandic glacier. Despite problems such as flight cancellations and equipment failures during the preparations, they finally arrive in Iceland. In Reykjavik, they enjoy the beautiful scenery, experience local life, and discover mysterious books in bookstores. Following the clues, they find a cave behind an abandoned church and what are suspected to be the remains of ancient Icelandic sacrificial rituals. At this time, they encounter an archaeological team led by Eric and a cultural relic trafficker. After a fight, they successfully protect the remains. Later, they discovered mysterious stone platforms, symbols and mysterious people in the ruins. They experienced many dangers, got into trouble with people claiming to be explorers, encountered attacks by strange creatures, and were repeatedly driven into a dead end. They worked hard to explore the secrets of the ruins and protect the mysterious power.
