Plot Summary:Witness to a mob killing and afraid to testify, young Louise Graham flees to Montana where she hopes to disappear working in the gift shop at Glacier National Park. Staying at the park are vacationers Matt Hallett, ex-marine, and Paul Adams, amateur photographer, both obviously very interested in Louise and both vying for her attention. Louise is unaware that one is a mob hitman, hired to kill her to prevent her from testifying, and the other is a cop working for the New York D.A.'s office, sent to protect her.
原来这一切都是因为3D……这片也可以算是为视觉奇观牺牲剧情合理性的典范了，关于一部纽约犯罪片如何变成了大西北登山电影。正常的城市犯罪片开头，还奇怪编剧怎么突然想不开跑到了蒙大拿度假村；毫无必要的山体滑坡和山火段落；高潮追逐部分以high sierra开始以垂直极限结尾……“保护被追杀的目击证人”这个主线到最后谁还记得么。
