Bloodtide

An American treasure hunter, Frye, arrives on a secluded Greek island searching for valuable artifacts. He encounters a young couple, Neil and Sherry, who are also visiting the island in search of Neil's missing sister, Madeline. As they explore, they uncover local legends about a sea-dwelling creature that was sealed in a cave long ago by ancient civilizations. Skeptical but intrigued, Frye ventures into the cave and inadvertently awakens the monstrous being. This triggers a series of mysterious and dangerous events that unsettle the island's superstitious villagers.

As tensions rise, the group learns more about the creature and its ties to the island’s history. The villagers, led by a reclusive older woman, seem to regard the entity with a mix of fear and reverence. Meanwhile, Frye's reckless greed threatens to undo any hope of resolving the ancient curse. With time running out, Neil, Sherry, and Madeline must navigate both natural and supernatural threats to put an end to the island’s terror. Their fate intertwines with the creature’s as they search for a way to restore peace to the island.
