Four artists from different backgrounds, including Jiang Haowen, Cai Sibei, Yue Wenle, and Lin Shengbin, visited South Yemen, Socotra Island, the Great Barrier Reef of Queensland and the Red Earth Region of the Northern Territory on their own, with little help from others, to discuss four major thinking topics in life. What's the scariest thing about life? Who is life for? Does Character Determine Destiny? In the uninhabited world, every artist asks himself with the most sincerity and without any harassment, and has a real "Dialogue with Heaven and Earth", opening his true heart to himself.
