Killer Mermaid (2014)

In the sun-drenched scenery of Montenegro, two American girls embark on a vacation, eager to reconnect with an old friend. Their trip takes a thrilling turn when curiosity lures them to Mamula, a desolate island housing an eerie, abandoned military fortress. As they probe deeper into the fortress's chilling past, they quickly realize that the island’s solitude is a deceptive mirage. An unseen guardian haunts the island, fiercely protective of the fortress's enigmatic secrets and shrouded in a darkness as profound as the fortress itself. What begins as a leisurely adventure spirals into a pulse-pounding fight for survival as the girls grapple with the terrifying reality of their situation. Beneath the fortress, hidden in the turquoise depths of the Mediterranean, lies a deadly siren - a killer mermaid. Once the stuff of fairy tales and sailors' whispers, the mermaid's watery lair becomes a horrifying reality for the unsuspecting girls. As terror engulfs their once carefree vacation, the girls must band together to escape the island's gruesome secrets before they become the mermaid's next victims. In the face of unspeakable horrors, their fight for survival becomes a desperate struggle against an ancient evil lurking beneath the surface.
