视频简介
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].。宇航员萨姆·沃克在完成自己第一次太空任务后重返地球的途中不幸坠入大西洋深海。尽管航天局派出许多救援队进行了长时间的救援后仍未找到萨姆。就在众人准备撤退放弃时，萨姆却奇迹般地出现，幸存了下来。萨姆的这次经历实在让人难以置信。航天局虽然准许她回到家里跟丈夫团聚，但是却受到了NASA的严密监视以及威廉·哈里斯将军的控制，开始在一座戒备森严的屋子里完成康复和医学检测。当周围接二连三发生了令人不安的事件时，她开始怀疑有外星人跟自己回到了地球。而此后她又渐渐地发现自己的身体机能发生了变化。她的反应、肌肉力量都得到了明显的加强。随着哈里斯将军地深入调查，真相付出水面，原来现在的萨姆其实已经是一个外星人了，而真正的她则永远的沉睡在海底。。
