Emily's daughter, Heather, avoids going home for Christmas in favour of celebrating with her boyfriend in Arizona. Heather doesn't know this, but Emily decides to surprise her daughter by coming to her in Boston over Christmas. At the same time, Charles, who lives in Boston, has writers block and needs a change of scenery. They get in touch on the internet and decide to switch places over Christmas. Once in Boston, Emily discovers that her daughter has gone away and she is also surprised by Charles' brother, Ray, who thinks she broke into Charles' apartment. Meanwhile, Faith, Emily's best friend, has decided to surprise Emily, who she thinks is celebrating Christmas alone at home, by visiting her. Faith, of course, finds Charles there to her surprise.
Despite double stories (or maybe even three), this film works well. A lot about opening up to new thinking.
