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].。《憨憨公主的心思》原名Connasse, princesse des coeurs,又名憨直公主的心,是一部来自法国的喜剧电影。讲述了一个低社会阶层的女人决定嫁给一个富有又有权利的男人,如果成功,她将不用再努力的工作,并且拥有自己所梦想中的一切的故事。此外,这部憨憨公主的心思的剧本创意和后制作都很有意思,它使用了隐藏的相机去拍摄路人的反应。这部电影中除了女主角是在演戏外,其他人的反应和对话都是真实的,这也是本片最大的亮点。。
