Mia Sullivan (Monica Calhoun), wife of Lance Sullivan (Morris Chestnut), has written letters requesting that the old gang should join them for Christmas: Harper Stewart (Taye Diggs) and his almost-nine-month-pregnant wife Robyn (Sanaa Lathan), Julian "Murch" Murchison (Harold Perrineau) and wife Candace Sparks (Regina Hall), her best friend Jordan Armstrong (Nia Long) and boyfriend Brian McDonald (Eddie Cibrian), Quentin "Q" Spivey (Terrence Howard), and Shelby Taylor (Melissa De Sousa). All the friends arrive at the house, the first time they've come together in 14 years, and the celebration begins. At dinner, the old friends catch up while tensions grow between Shelby and Candace. Years after his debut novel, Harper is struggling with writer's block, financial difficulties, and pressure from his publisher to come up with newer and better material for his next book. He has also been recently relieved of his faculty position at New York University, further complicating the couple's financial position. He kept all this from Robyn, as she is finally pregnant with their first child after years of expensive fertility treatments and the baby is almost full-term. His agent suggests he write a biography on his estranged friend, Lance, who is set to retire from football. Harper reluctantly agrees, but keeps the biography a secret..
