Hinatsugimura

A group of university students ventures deep into a remote mountain wilderness, driven by their search for the ruins of a village that existed before the Second World War. Their expedition takes an unexpected turn when a violent thunderstorm suddenly strikes the region, leaving them stranded far from civilization. With cellular service completely unavailable and no means of contacting the outside world, the students are forced to seek immediate shelter from the relentless downpour. Their search leads them to a large, isolated mansion standing quietly amidst the rugged terrain. Believing they have found a safe haven to wait out the severe weather, the group decides to take refuge within its walls. However, the temporary relief of escaping the storm blinds them to the true nature of their surroundings. What initially appears to be a stroke of luck soon reveals itself as a trap, as a terrifying and ghastly fate awaits the unsuspecting students inside the mansion.
