This Christmas is a dramatic comedy that depicts the story of the Whitfield's, a family that has not celebrated the holidays together in many years. Ma Dear (Loretta Devine), the matriarch of the group, still lives in the home her children grew up in. Quentin (Idris Elba), the first-born, is a jazz musician who has trouble paying his debts. Lisa (Regina King) has settled into an unhappy marriage and resents her younger sister, Kelli (Sharon Leal), for taking advantage of opportunities that Lisa was never able to enjoy. Claude (Columbus Short) manages to take a break from the Marines to arrive home for the holidays but refuses to allow his girlfriend to meet his family. Youngest sibling Michael (Chris Brown) has dreams of becoming a singer, but fears his mother will not approve. Each member of the Whitfield family is harboring a secret, and as the film unfolds, their relationships with one another are put to the test.
