American psychologist John Holden arrives in London to participate in a symposium aiming to expose witchcraft and devil-worship as a fraud, with attention centered on a cult run by a Julian Karswell. Debarking his plane, Holden learns that the symposium leader, Henry Harrington, has suddenly died and he is now in charge. What only the audience knows is that Harrington was clearly killed by a demon, apparently summoned by Karswell to avenge his persecution. Despite both threatening and cajoling behavior by Karswell, Holden determines to proceed, though the only cult member willing to talk about his experiences is in a prison psychiatric ward, catatonic after allegedly killing yet another cult member. However, Harrington's niece, Joanna, believes, based on her uncle's notes, that Karswell may indeed have some satanic powers derived from an ancient tome in an obscure language which he has been able to translate, and attempts to warn the skeptic Holden. Karswell's mother also attempts to warn Holden off. However, the thing which begins to most get to Holden are the occasional, but mounting, sensory and mental disturbances he begins experiencing after an encounter with Karswell, and the discovery that, during this encounter, Karswell secretly slipped a slip of parchment with a curse in runic symbols on it into Holden's belongings, a parchment identical to one Harrington recorded having had passed to him in a similar manner shortly before his death... [N.B. Holden at no point stays at the Karswell estate].。独自居住在一桩高档公寓中的真壁铃音(内田有纪 饰)是一名小有名气的电视剧编剧,她的作品备受好评,现实生活中又与制作人柳井抱持着相敬如宾的不伦关系,亦可为顺风顺水。谁知这一切在某个雨夜画上句号。这一晚铃音的高中同学古泽水绘(池胁千鹤 饰)拖着六岁的儿子不请自来,她和铃音曾在高中的合唱部待过,当下铃音所写的剧本正以高中这段经历为蓝本。作为关系并不亲密的二人,水绘的前来让铃音颇感错愕,但出于礼貌她还是将对方留在家中。本以为只是短暂借住,谁知不速之客却因各种理由留了下来,还让铃音本来平淡的生活乱作一团……
