It's Christmas in Newport. The mansions are decorated, and the streets are filled with excitement. Across the bay, preparations are in full swing for the wedding of Meri Calder-Hollis and Alden Corrigan. A year ago, Meri never imagined that she would marry her best friend, Alden, or become stepmother to his two teenaged children, Nora and Lucas.

But as the wedding day draws near, tension and emotions run high, and Meri's happiness turns to uncertainty. Nora is suddenly acting sullen and withdrawn, Alden is preoccupied, and Meri wonders if her marriage will bring the family closer together or tear them apart.

It seems like this wedding may be doomed before it begins until a special Christmas surprise brings home the meaning of family and the joy of the holidays.
