回复 :真相与幻想之间的界限是什么？感官是否能助我们认识世界？影片用一个摄影师的故事，铺开了一系列哲学、心理学的问号。主角是摄影师托马斯(戴维·海明斯 David Hemmings饰)，某天他在公园里抓拍到年轻情侣的系列照片，出人意表的是，照片中的一个女子简(瓦妮莎·雷德格瑞夫 Vanessa Redgrave饰)竟然不惜一切代价要回她的底片。这让托马斯非常疑惑，他相信这张照片许是拍下了某些不可告人的秘密。果然，他把照片放大后，看到了一具尸体和一个拿着枪的人。一桩谋杀案的雏形在托马斯脑中展开。他前往公园寻到了尸体，但没有人肯相信他的推测，朋友们不愿意和他一起调查这是怎么回事。第二天，当托马斯再次来到公园，发现尸体已经消失无踪。只剩下一群人进行着一场虚拟的网球赛，打着并不存在的的网球。
回复 :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].
