The luxury cruise ship Xinglan capsizes in a tsunami, leaving only outdoor engineer Jiang Yuanshan and seven women stranded on a deserted island. Jiang Yuanshan awakens a deserted-island survival system and uses his professional skills to establish a cave camp, but the arrogant Shu Manting drives him away, while dessert blogger He Tang chooses to follow him. With food running low and no fire, everyone suffers through hardship. As a typhoon approaches, Shu Manting has no choice but to swallow her pride and ask for help. When the typhoon strikes and wild beasts attack, the eight survivors work together to overcome the crisis. Shu Manting finally realizes her mistakes, and the group becomes a harmonious team. Just as everyone begins to hope for rescue, an old lifeboat carrying four malicious drifters lands on the island, forcing the survivors to confront the dark side of human nature.
