Five campers arrive in the mountains to examine some property they have bought, but are warned by the forest ranger Roy McLean that a huge machete-wielding maniac has been terrorising the area. Ignoring the warnings, they set up camp, and start disappearing one by one. If that sounds too run-of-the-mill, there's a genuinely shocking plot twist half-way through... 史上最好的25部恐怖片之一的影片讲述了五个露营者所遭遇的惊险故事，他们上山来查看他们买了的物产, 而森林守护员Roy McLean警告他们要小心, 一个拿着大刀的疯子在该区出现。他们忽略警告,设定了营幕, 一个一个逐个消失。这部影片给观众带来摇滚乐般的心跳节奏，满足了影迷们对恐怖片的需求，给人留下了深刻的印象。影片中除了恐怖的情节外，还有参加露营的俊男靓女们的关系描述，再加上对他们逃避追杀，并努力生存的过程叙述，很好的丰富了影片的剧情，不愧为恐怖影片史上的经典之作。
