A sudden explosion caused the expedition cruise ship Blue Whale to sink into a storm. Former sea rescue team member Shen Yan and nine survivors drifted onto Whalebone Island. There is no fresh water, no food, injuries and typhoons approaching step by step. But when they found the still-heating camera and the battery that had just been replaced in the uninhabited jungle, everyone realized: someone on the island had been watching them. Survival is just the beginning, the real danger is the lighthouse plan behind this shipwreck.
