马德里1987

　　佐藤铃（道本成美）为了逃避母亲（南久松真奈）的过度干涉，在川上信夫（泉知束）的引导下，前往东京的一处房产进行内览。尽管被告知前住户山本孝雄（岩永ひひお）因欠租而失踪，铃仍被这处优质房产所吸引。信夫提议她单独继续内览时，铃顺从了他的建议。然而，她在房中听到某种不祥的声音，被引导着打开了一扇通往异世界的门，随后被强行拉了进去。醒来后，她发现自己身处一座荒废的巨大建筑中，迷茫中遇到了自称山本孝雄的男子。这个空间被某个怪物所支配，既无法逃脱，也无法死去，真正的无间地狱。

　　

　　Driving home late at night during a heavy rainstorm, Glen experiences car trouble. Near where his car gets stuck, he spots a house, knocks on the door and is greeted by an oddly friendly middle-aged man, Arthur, and his younger wife, Cyndi. The strange couple pours him a drink, and then more drinks, followed by an unexpected offer that Glen can’t refuse. Elsewhere, a young woman, Katie, is feeling emotionally weighed down by a secret romantic arrangement that feels like a textbook case of gaslighting. And at the same time, in a nondescript research facility, medical professional Julie begins questioning her role in a bizarre experiment, fearing that she’s doing more harm than good.
