Bikini Shark

Jessica, a marine biology student, arrives on a tropical island to study coral reefs. Her peaceful research descends into nightmare when a predator unlike any known creature appears in the lagoon. Locals whisper about an ancient curse, while tourists continue swimming carelessly in bikinis, unaware of the danger. As disappearances multiply, Jessica uncovers a connection between underwater caves and strange mutations in marine life. Teaming up with a surviving guide, she must not only survive but stop the creature before it reaches the open ocean. The film blends ecological thriller with slasher elements, where the greatest threat hides not in the depths but in the crystal turquoise water just offshore.
