A tropical resort is set up on an exotic island inhabited by indigenous tribes. The resort’s owner, determined to exploit the island’s natural beauty for profit, dismisses the warnings of the local tribespeople, who believe a vengeful spirit resides in the nearby river. When a series of mysterious and brutal attacks begin to plague the area, the resort's guests and staff are thrown into a state of panic. A photographer, initially there to document the resort's new opening, starts investigating the strange occurrences.

As the attacks become more frequent and deadly, it becomes clear that the threat is not just superstition. The local tribe’s legend speaks of a massive alligator, considered a guardian of the island, that has become enraged by the intrusions into its territory. The situation escalates into chaos as the resort’s inhabitants struggle to survive against the monstrous predator. Fear and desperation grow, leading to a tense showdown between man and nature. As the humans try to find a way to escape, they begin to understand the gravity of their disrespect towards the island and its mystical guardian.
