Uninhabited

Beth and Harry arrive on a deserted coral island and set up their camcorder to document their ten-day trip. In the first two days, they sense they are not alone and uncover a disturbing history: an abandoned grave beside an old shack, seven tally marks on the wall, and a wooden cross bearing the name Coral. The island’s atmosphere quickly turns from idyllic to ominous as these clues accumulate.

While reviewing footage, they discover they have been filmed sleeping, which unsettles Beth. She clearly wants to leave, fearing danger, while Harry insists they should stay and that the strange events are probably pranks. The tension between them deepens as the mystery of the island grows.

The couple glimpses fishermen on a boat armed with guns, heightening the sense of danger. They later notice that the grave outside the shack has been remodeled, adorned with red coral and a wooden cross bearing the name Coral. The island’s past becomes personal and threatening.

They find severed sea cucumbers hanging from a line, signaling a grim local activity. The realization that they are targets grows as their phone—intended for a rescue call—disappears. The sense of isolation deepens with each disturbing clue.

Snooping around the fishermen’s space and boat leads to Beth and Harry being tied up, and Beth is sexually assaulted. A female ghost appears and injures one of the men, causing the fishermen to flee in their boat. The couple manages to free themselves, shaken and more frightened than ever.

Beth finds an old journal in the shack and learns Coral’s backstory: a young island girl who harvested sea cucumbers in the 1920s, was ridiculed and raped by seven men, and died violently. Since then, her vengeful spirit has haunted anyone who visits the island. The story reframes the danger as a supernatural retribution against men.

Realizing their predicament, Beth and Harry decide to create a large bonfire to attract rescuers. They gather materials and prepare the site, attempting to keep hope alive. The plan hinges on a possible rescue that may never come if they fail to be found.

A ringing phone lures Harry to the shack, where Coral ambushes him with a knife. He is killed and his naked body is hung from a tree above Coral’s grave, a brutal sign of Coral’s continued vengeance. Beth discovers the grim scene and faints from shock and fear.

The following morning, Beth learns Harry’s body is missing but one grave near the campsite has been filled in. As she lights the bonfire, Coral appears on the reef, and Beth tries to confront the apparition. She runs toward Coral, steps on a venomous stone fish, and endures a painful attack as she struggles back to shore.

On the tenth day, Jackson returns to pick up the couple but finds no one in sight. He enters the shack and discovers the journal, setting the stage for a final confrontation. A menacing Beth appears and presumably kills him, and the closing image shows Beth’s grave beside Coral’s, hinting that the two may have joined forces.
