Harry Connick Jr. stars as Michael Walker, who, as a child, wished every day could be Christmas. That is, until a tragic accident crushed his holiday spirit. Thirty years later, Michael still can't muster any joy for the holidays, despite encouragement from his playful wife (Connie Britton) and well-intentioned parents (Kris Kristofferson, Fionnula Flanagan). But when his young son (Chandler Canterbury) faces a tragedy, Michael needs to make amends with his past. A mysterious man named Nick (Willie Nelson) gives Michael a gift and instills in him the courage to find the joy that he lost.
