Hit comedy director Tang Xidiya, whose brain was injured by an accident, once hovered on the brink of life and death. During this period, he developed a strong interest in exploring life. After recovering, he decided to fly to various places with the four-member film crew to visit outstanding people from different fields, including writers, scholars, religious leaders and scientists, focusing on two basic questions: first, what is wrong with our world? Second, what can we do? This documentary not only discusses human nature and the influence around our team, but also brings out the positive message that "as long as everyone takes a small step, the world can be changed."
