The episode is dedicated to the memory of Margaret John, who played Doris, who died in February 2011.

Eleven years have passed since Gavin and Stacey went to Billericay to spend Christmas with the Shipmans and the Wests. This year, since everyone is in Wales for the festivities, Bryn is cooking the dinner for over 13 people. Pam would secretly prefer to spend Christmas in Essex, as she finds Gwen's house a bit lacking. The deal has always been that they alternate every year, and this time it's the turn of the Wests to host Christmas. Gavin and Stacey are now parents of three children Harri, Caitlin and Megan, but Stacey worries their relationship has lost the excitement of the early days. Smithy, too, continues to commit to his fatherly role, making the journey to Barry on at least alternate weekends to see a now 11-year-old Neil.

At the end, Nessa confesses to Smithy that she is in love with him, getting down on one knee to propose, concluding the special on a cliffhanger.
