Christmas is supposed to be a time for peace and joyful family reunions. But when Matt and his wife Karen show up unannounced at the home of his estranged brother Steve to celebrate the holidays, they are instead greeted with a horrifying surprise: trapped in the basement is a man. But not just any man. Steve believes that his hostage is none other than the devil himself. 　　译文(2): 圣诞节应该是一个和平和欢乐的家庭团聚的日子。但是当马特和他的妻子凯伦突然出现在他疏远的弟弟史蒂夫的家中庆祝节日时，他们却被一个可怕的惊喜所取代: 一个被困在地下室的男人。但不是随便什么人。史蒂夫相信他的人质就是魔鬼本人。
