A journey into ancient terror begins when a group of young American friends, led by the adventurous Logan Huffman and Brandon Tyler Sklenar, travel deep into the Japanese countryside. Their destination is a forgotten temple, shrouded in local legend and strictly off-limits, driven by a mix of reckless curiosity and the desire to document the unknown. Accompanied by Natalia Warner, they soon discover the site holds a malevolent force far more dangerous than any ghost story. As they delve deeper into the temple's cursed history, the friends find themselves trapped in a nightmare where the ancient structure's horrifying secrets begin to awaken. Directed by Michael Barrett from a script by Simon Barrett, this chilling horror film masterfully builds an atmosphere of dread, pitting modern arrogance against a primordial evil that guards its sanctum with a vengeance. The temple does not give up its visitors easily, and survival becomes a desperate race against a power they were never meant to disturb.
