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].。上世纪三十年代，有一个神秘的龙关村隐藏在群山深处，数百年来由龙氏一族独居，历代族长都恪守着一个祖传秘密，生不吐露，临死口传！一并相传的，还有一把能够打开生死之门的钥匙！而天下没有守得住的秘密，朝代兴替，传至民国，时逢中原大战，四方动乱，一个外姓人趁机钻进了龙关村，潜伏数载，终于摸清了龙氏家族的秘密。在妻子儿子被挟持的逼迫下，这个外姓人昧着良知将龙家机密泄漏出去，于是，一座被龙氏家族死守数百年、埋藏着前朝邪教至高权力、无尽财富的磐石毒墓随之浮出水面……。
