Death Bell (2008)

In the heart of Seoul, within the walls of an elitist high school where grades and pedigree reign supreme, a chilling scenario unfolds. In an effort to prepare for a looming visit from British scholars, favored teachers Mr. Kim and Ms. Choi gather the crème de la crème of their pupils for a Saturday study lock-in. However, this academic pursuit quickly spirals into a nightmarish ordeal as students begin to mysteriously vanish, meeting grim ends that are gruesomely projected to the remaining members via the school's CCTV system. With the school transformed into a claustrophobic trap by an ominous voice emanating from the P.A. system, the terrified students and their teachers are warned of certain death awaiting any who dare to leave. But this malevolent voice isn't merely content with casting fear — it poses riddles, cryptic questions that Mr. Kim and his students desperately try to decode in a bid to save their peers. As the terrifying saga unfolds, viewers are left to question if this nightmarish ordeal will ever cease. Is the force behind it grounded in reality, or does it lurk in the realm of the supernatural? What, if any, is the pattern behind this string of gruesome incidents? The plot of Death Bell rings with suspense, leaving the audience pondering these enigmas, a chilling melody echoing long after the final scene.

Death Bell is a horror movie featuring Lee Beom-soo.
