It's Ed and Sarah's first night at their new home - an isolated farmhouse on the Scottish borders. This should be a new beginning away from their stressful London lives. And at first it is; come sunset they fall in love all over again on a wander in the woods. But as darkness falls, Sarah suspects they're not alone, Ed goes to investigate and quickly, the evening becomes a nightmare. It suddenly dawns on them; they do not belong here. And they certainly aren't welcome either.... 　　译文(2): 这是艾德和莎拉在新家的第一个晚上苏格兰边区上一个与世隔绝的农舍。这应该是一个新的开始远离他们紧张的伦敦生活。一开始是这样的; 日落时分，他们在树林里漫步，再次坠入爱河。但随着夜幕降临，莎拉怀疑他们并不孤单，艾德去调查，很快，夜晚变成了噩梦。他们突然明白了，他们不属于这里。他们当然也不受欢迎。
