阖家团圆的圣诞节即将到来，但年轻而又富有的小伙子德鲁（本·阿弗莱克 Ben Affleck 饰）却陷入了忧郁之中，因为他不仅举目无亲，而且深爱的女友在不久之前离开了自己。华灯初上的街道和对节日期待满满的市民们更加深了德鲁的思乡之情。 德鲁有过一段十分美好的童年记忆，为了重温这段记忆，德鲁决定重返自己曾经居住过的老房子。现在正住在这所房子里的，是汤姆（詹姆斯·甘多菲尼 James Gandolfini 饰）和克里斯汀（凯瑟琳·欧哈拉 Catherine O'Hara 饰）夫妻两，这个家庭显然并不欢迎德鲁这位不速之客。于是，德鲁拿出了他仅存的资本——钱，买下自己和这一家人共度圣诞的权利。It's the Christmas season. Wealthy Chicago ad executive Drew Latham has long avoided the family traditions of Christmas, but has dreaded being alone on the actual day. So when his tropical Christmas vacation with girlfriend Missy Vangilder falls through with Missy breaking up with him in the process, Drew, in going through some self-therapy, decides what he really needs is to relive the memorable Christmases from his childhood, which includes spending time with his parents and younger brother. As that is not possible, he decides to rent a family, namely ones he's never met before, the Valcos - husband and wife Tom and Christine and their teenaged son Brian - who now live in Drew's childhood home in suburban Chicago. Tom initially wants nothing to do with Drew until an exorbitant sum of money is involved, all written in a contract which expires at the end of Christmas day. What Drew is initially unaware of, or what he chooses to remain ignorant about, is that the Valcos are going through their own family problems, which are only exacerbated by Drew's presence. For the Valcos, the questions become whether they can endure Drew's stay until the end of Christmas day, and if they can if the money will solve their family problems. In the process, Drew may come to an admission to himself of what he wants in life and perhaps how best to achieve it. The achieving it may be difficult if he doesn't fully know that life, and as external forces come into play to complicate matters.
