In the 1970s, on the Binlusai islands, a young mother is killed as she flees an ominous presence inside an abandoned Roman Catholic leper colony, a haunting echo of a dark past that lingers over the place. In the present day, eight travelers arrive on the same island to take part in a survival game organized by the TV channel Search Planet, led by Chen Jiadong. On board the boat, the lineup includes the TV presenter Stanley and the cameraman Ken, all eager for a prize that could change their lives. The eight contestants are split into four pairs, each pair handed a map that supposedly leads to a hidden flag, with a one-million-dollar grand prize for the winning duo. The air crackles with competitive energy, but tension soon mixes with something more primal as they close in on the island.
As they approach shore, the voyage is disrupted by an unseen force beneath the water, tearing at their boat and scattering their supplies. On land, the group faces immediate danger from feral boars that stalk the jungle; a fellow competitor, Ono Hiroshi, proves his prowess by felling one of the tusked beasts with a hunting knife. The night deepens the mystery as they stumble upon the ruins of the long-forgotten leper colony. Inside a chapel, a stark message scrawled on a stained-glass window hints at grim fates ahead: the truth they seek may come at a deadly cost. Funeral urns bearing each participant’s name line the rooms, turning the colony into a chilling memorial.
Tensions flare as alliances form and motives collide. Guan Zhichun and Tina press Peng Fei to surrender the map, while Shen Yilin insists that the map be returned to her, determined to protect her partner. The pressure escalates when Peng Fei suddenly vanishes after a confrontation with the group’s forces, leaving a growing sense that something unseen is orchestrating fear and betrayal. Meanwhile, Chen Liangliang uncovers a notebook hidden within the ruins, a clue that seems to bind the night’s events to a longer memory of the island. Zhang Xiaolong tries to piece together what’s happening, but a wave of unconsciousness sweeps over everyone, leaving the fate of the group uncertain.
The morning after, the atmosphere sours further as Shi Nan is found with blood on his shoes, denying any role in a supposed killer’s actions. When [Chen Liangliang] disappears with the notebook she uncovered, the group fractures into suspicion and panic. As the survivors scramble to understand the inexplicable turn of events, they must confront not only the dangerous environment but also the unsettling history that haunts the island, a history that seems to be rewriting itself through fear, secrets, and the fragile threads of trust.
The island’s eerie quiet is punctured by sudden realizations: past tragedies echoing into the present, a treasure hunt that may demand more than courage, and a survival game where the ultimate prize could prove to be the cost of knowing too much. In this tense blend of mystery and danger, the contestants navigate a maze of hidden motives, shifting loyalties, and a malevolent force that seems to know their every move, leaving viewers with a chilling question: who will survive not just the game, but the island’s haunting memory?
