黑暗侵袭2

美国阿巴拉契亚山脉的查图嘎国家公园岩洞群，朱诺（Natalie Jackson Mendoza 饰）、莎拉（Shauna Macdonald 饰）一行六人在此经历了一生中最恐怖的时刻，最终只有莎拉一人侥幸逃生。在此之后，警方派出大批搜救人员进山寻找遇难者的尸体以及可能的幸存者，但是最终却一无所获。女警官萝丝（Krysten Cummings 饰）负责询问莎拉失踪事件的始末，但是莎拉对过往发生的事情没有任何记忆。为了寻找幸存者和事实真相，萝丝带着莎拉再次来到岩洞群，并在此与搜救人员凯西（Anna Skellern 饰）和格雷格（Joshua Dallas 饰）等碰头。他们从废弃的矿井口进入岩洞，不久便发现贝丝等人的尸体。搜救人员意识到这不是简单的失踪事件，与此同时危险正向他们悄悄逼近……Distraught, confused, and half-wild with fear, Sarah Carter emerges alone from the Appalachian cave system where she encountered unspeakable terrors. Unable to plausibly explain to the authorities what happened - or why she's covered in her friends' blood - Sarah is forced back to the subterranean depths to help locate her five missing companions. As the rescue party drives deeper into uncharted caverns, nightmarish visions of the recent past begin to haunt Sarah and she starts to realize the full horror and futility of the mission. Subjected to the suspicion and mistrust of the group and confronted once more by the inbred, feral and savagely ruthless Crawlers, Sarah must draw on all her inner reserves of strength and courage in a desperate final struggle for deliverance and redemption.
