In a rare sea storm, wealthy businessman Chen Hao, female reporter Yang Min, fisherman Gan Yuanxiu, female painter Li Wei and retired policeman Wang Dashan were trapped on a deserted island on the southeast coast-Qingyun Island. The dilapidated lighthouse and abandoned houses on the island hide unknown secrets. After the storm, Li Wei mysteriously disappeared and everyone fell into panic. During their investigation, Yang Min and Wang Dashan discovered strange symbols and hidden secret rooms on the walls of the lighthouse, which seemed to be related to the shipwreck many years ago. Gan Yuanxiu's abnormal behavior and the clues left by Li Wei imply that the truth is far more complicated than they imagined. As the investigation deepens, a story about greed, betrayal and redemption gradually emerges. Eventually, the truth is revealed, but at a heavy cost. "The Island" not only shows the struggle and growth of human nature in extreme environments, but also triggers profound thinking about the relationship between people and between people and society.
