匈牙利近郊东部山区，一趟误入歧途驶向死亡的恐怖之旅。国际知名军火公司“篱笆防御”集团的老总为了庆祝业绩创新高，特意为员工们举办了一次豪华温泉乡之旅，共度这个周末。然而这次旅程却并非像员工们想得那么奢华美好，接二连三发生的恐怖血腥事件，让众人如坐针毡，人人自危。当众人来到荒无人烟并被群山环绕着的边境地带时，就已经个个胆战心惊。更令他们毛骨悚然的是，他们过夜的地方居然是一间废弃破旧的精神病院。而更糟的还在后面，一群手持该公司军火的俄罗斯人对他们发起了疯狂的攻击。
　　由英国导演克里斯托弗·史密斯自编自导的恐怖喜剧电影《断头气》，构思精巧、情节跌宕起伏，时时冒出一些既恐怖又幽默的精彩瞬间。本片也是向大师斯坦利·库布里克的致敬之作。

　　A descent into Hell is triggered when "Ex-Lord" Donald Brocklebank finds that he must leave Longleigh House for London to find a way to pay for the medical treatments for his wife Nancy. Alone, his over-protected, delusional, adult son, James, fancies himself in charge of the manor house with his terminally ill mother, and barricades the two of them into the house for a series of ever more panicked home treatments, mistakenly protecting her from the arrival of Nurse Mary and any outside help. Written by Bob Lee
