Lihim(1997)

Lihim is a Filipino slasher film that follows a group of teenagers on vacation in an isolated coastal town. When a mysterious psychotic killer begins murdering them one by one, the survivors must race to uncover the killer's identity before they're all dead. Trapped in a remote setting with no easy escape, the teens face mounting terror as they piece together clues about who is hunting them and why. The film blends suspense with the claustrophobic dread of being hunted in an unfamiliar place, far from help. As the body count rises, paranoia sets in—no one can be trusted, and time is running out. Lihim delivers the tension and shock expected from the slasher genre while grounding the story in a distinctly Filipino setting.
