Lin Ye, a delivery driver in City S, clutches the money he's scraped together for a plane ticket and rushes to his coastal hometown to see his critically ill father one last time. Su Wan, a campus beauty studying finance at a top university and the daughter of an ultra-wealthy family, sets off on a trip to clear her head after her boyfriend, Xu Haochen, and her best friend, Lin Lin, betray her. Neither knows that a major disaster awaits them.
At an altitude of ten thousand meters, a mysterious force pulls their plane into a parallel world, and it crashes onto a gigantic deserted island. The sweltering tropical rainforest alternates with winter blizzards ten degrees below zero. The 21 survivors are forced to face deadly dangers: ferocious beasts surround them, bloodthirsty cannibals stalk them, and a savage primitive tribe, as formidable as the Aztec civilization, eyes them hungrily.
A vast freshwater lake at the island's heart offers a chance at survival, but its branching waterways have become the domain of competing forces: cannibals, primitive tribes, and modern people stranded there by air and shipwrecks from different eras, all watching one another warily from the lakeshore.
Though strangers, Lin Ye and Su Wan depend on each other in this desperate situation: he brings the grit of someone who has fought to survive at the bottom, while she contributes intelligence and resources. They must solve the island's mysteries, fend off threats from every side, and watch out for the ruthless schemes of the traitors behind them. Only by facing death together can they hope to escape the island that devours lives.
