A middle-aged, married couple retreats to a secluded vacation cabin, hoping to mend their strained relationship. From the moment they arrive, they are given one rule: the door at the end of the hall is strictly off-limits. At first, the husband is mildly curious, but as the days pass, the door seems to call to him. Strange occurrences - whispers in the night, fleeting shadows, objects not where they were left - slowly unravel his sanity. His curiosity festers into obsession, consuming his every thought. What lies beyond the door? The answer may be far more terrifying than he ever imagined. This psychological horror film thrives on an eerie, slow-burning tension, unsettling atmosphere, and the creeping dread of the unknown.
