John Goodman and Diane Keaton star in this festive romantic comedy. On Christmas Eve four generations of the Cooper family reunite to spend the holiday season together. Although matriarch Charlotte Cooper (Keaton) just wants everyone together to enjoy the perfect Christmas, the holiday celebration doesn't quite go according to her plan. Before the festivities even get under way, her daughter Eleanor (Olivia Wilde) convinces a stranger to pose as her new boyfriend for the weekend, her sister Emma (Marisa Tomei) is arrested for shoplifting and their brother Hank (Ed Helms) is struggling to cope with single parenthood. With the whole family under one roof, Charlotte's dreams of a perfect holiday are put in serious jeopardy.
