Lin Tong, a college classmate, formed a five-member expedition team to venture into inaccessible wilderness areas around the world in search of the lost miracle "Star Ruins." During the journey through wilderness, jungle, strange islands and mysterious realms, there are both non-human natural disasters and tests of humanity, trust and unity. The five people are good at each but have completely different personalities - they rub against each other, but they help each other through humor and ridicule. During the exploration, they gradually uncovered the mystery behind the ruins and discovered their own courage and growth. In the cliffs, they use ingenuity and optimism to deal with the crisis; in the dark and mysterious realm, they break through the difficulties with faith and friendship. In the end, the team uncovered the ultimate secret of the Star Ruins and realized their own growth and change.
