Widow Emily is looking forward to Christmas, when her daughter, Heather, comes home from Harvard to Leavenworth, Washington, an idyllic small town that goes all out for the holiday. When Emily finds out that Heather has no intention of spending Christmas with her, she calls her friend, Faith, for sympathy, then decides to surprise her daughter in Boston. No rooms are available, so she tries a Web site that exchanges houses.
Emily trades her house for two weeks with an absentminded professor who hates Christmas and then is on her way. Then Faith makes a surprise visit to Emily and is surprised instead. Heather leaves with a biker dude for Florida; Faith then hitches a ride with an acting troupe dressed as elves. Add a Pomeranian and a lobster, and hilarity ensues, as does romance in this fast-paced, lighthearted, and charming Christmas story, a tale as joyful as the season itself.
