Mysterious Island

Present-day eight travelers set out for the Binlusai islands to participate in a no-supplies survival game for a million-dollar prize. They travel by boat with the TV channel Search Planet, led by Chen Jiadong, along with a presenter and cameraman. The mood is a mix of excitement and unease as they approach the unknown island.

As they near the shore, their ship is attacked by something beneath the water, throwing the passengers into chaos. Much of their luggage washes away or sinks, forcing everyone to improvise with what remains. The looming island becomes a more immediate and dangerous backdrop to the game.

Shen Yilin keeps her map intact and passes it to Peng Fei, ensuring at least one guide survives the initial commotion. The map's survival marks the beginning of a contested resource among the pairs. The group will rely on it to navigate toward the flag and the promised prize.

They are attacked by wild boars on the shore or inside the forest. Ono Hiroshi kills one boar with his hunting knife, demonstrating the immediate perils of the island's wildlife. The encounter adds urgency to secure supplies and navigate the terrain.

That night, the group discovers the abandoned leper colony's chapel and ruins, shrouded in ominous silence. A message written in Chinese on a stained-glass window warns that they will be killed, setting a chilling tone for the game. Funeral urns appear, each bearing a traveler’s name, heightening paranoia and fear.

Guan Zhichun and Tina pressure Peng Fei to relinquish the map, while Shen Yilin urges him to return it to her. The confrontation reveals shifting alliances and the stakes of control over the game's most valuable clue. The tension foreshadows further danger as trust frays.

Peng Fei is attacked by an unseen force and vanishes, leaving the others in shock. The loss of a participant makes the competition suddenly personal and terrifying. The mystery of who or what is targeting them deepens the sense of peril.

Chen Liangliang discovers a notebook hidden within the building, suggesting there are hidden clues or a deeper backstory to the events. The notebook raises questions about who has planned the traps and what the other pages might reveal. The group begins to suspect that the danger is not merely random.

Zhang Xiaolong proposes a method to deduce what is happening, trying to connect the eerie clues and symbols to identify the killer or the next threat. The plan signals a rational approach amid rising panic, but trust remains fragile. The idea itself becomes another point of contention within the group.

Almost immediately after Xiaolong's proposal, everyone suddenly passes out, plunging the group into darkness. When they awaken, they must cope with disorientation and fear, unsure of what occurred during the blackout. The incident raises questions about who among them is responsible.

Morning reveals Shi Nan with blood on his shoes, yet he denies being the killer. The suspicious evidence fuels distrust among the survivors and invites accusations. The tension heightens as the mystery of the earlier events continues to unfold.

Liangliang goes missing along with the notebook, though the reasons remain unclear. The disappearance compounds the group's fear and fragments the dynamic, as potential clues disappear with her. The remaining members scramble to search for both the notebook and their missing partner.

Chaos erupts among the group as suspicion and fear drive people to act defensively. The survivors scramble to protect their partners in the survival game while unraveling the day’s secrets. The leper colony's warnings and the disappearances deepen the sense that someone—or something—inside the game is orchestrating the danger.

With Peng Fei missing, the notebook gone, and the looming threat unresolved, the survivors are left in a state of mounting uncertainty. The group must decide how to proceed while the ominous signs from the leper colony linger. The fate of the prize and the truth behind the deadly game remains unresolved as chaos reigns.
