Working in a Boston homeless shelter, Nick Flynn re-encounters his father, a con man and self-proclaimed poet. Sensing trouble in his own life, Nick wrestles with the notion of reaching out yet again to his dad.

Optometrist Steve Finch loves those Christmas traditions he has set up with his family and his town. As such, he has a schedule of activities for his family starting on December 1, and is the unofficial consultant for anything Christmas-related in his town of Cloverdale, Massachusetts. During the Christmas season, the Halls move into the house across the street from the Finches'. The Halls in general are different in outlook and temperament than the Finches. Unlike Steve, Buddy Hall scams his way through life and never follows through with anything he starts. While Kelly Finch and Tia Hall and their children begin friendships based largely on those differences, Steve and Buddy butt heads based on those differences. It begins with Buddy striving to have his house seen from outer space by decorating it as lavishly and brightly as possible. One of the results of Buddy's task is that he becomes the new go-to guy for anything Christmas-related in Cloverdale, usurping Steve's coveted position. As Steve and Buddy's open animosity grows, they may threaten the joy of Christmas for all, most specifically their families who have their own ideas of what they would like to do over the Christmas season.
