The 8th night

The 8th Night (2021) is a South Korean supernatural thriller based on an ancient Buddhist legend about a powerful demon whose two eyes — the Red Eye and the Black Eye — were separated by Buddha to prevent the gates of hell from opening. In the present day, archaeologists accidentally awaken the Red Eye, which begins possessing seven human bodies over seven nights, leaving a trail of mysterious deaths as it moves closer to reuniting with the Black Eye. The only person capable of stopping the apocalypse is Park Jin-soo, a former monk who once trained to guard the demon but abandoned his spiritual path. Forced to confront his past and his inner fears, he teams up with a young monk and a detective to stop the demon before the eighth night arrives. As the final confrontation unfolds, the film reveals that the true horror is not just the supernatural entity, but the darkness, guilt, and weakness within humans themselves, suggesting that evil survives by feeding on human fear and desire.
