GAVIN & STACEY: WATCH THE TRAILER FOR THE FINALE AHEAD OF CHRISTMAS DAY RELEASE ON BBC ONE

It’s five years since we left Nessa down on one knee declaring her love for Smithy and asking him to marry her. And a lot has happened in those five years.

In Barry, Bryn’s packing the Picasso in readiness for a trip to Essex; Stacey and Gavin are looking for new ways to spice up their seventeen year marriage and Gwen is behaving most strangely. Nessa’s started a new business venture and Neil the Baby’s about to begin an apprenticeship with his dad.

Over in Billericay Pam is stressing out at the prospect of playing hostess, not helped by a newly retired Mick practicing his golf swings in the living room and there have been more ups and downs in Pete and Dawn’s relationship.

Join us on the journey to Barry and Billericay as we catch up with the Shipmans and the Wests for the very last time and maybe find out what exactly did happen on that fishing trip.

After the special, an uplifting and touching documentary special which tells the story of one of Britain’s best loved sitcoms as it comes to an end after 17 years. It charts the journey of a little-known sitcom that started life on BBC Three which, with its blend of relatable characters and infectious catchphrases, grew into a must watch show that captivated the hearts of the nation.

Featuring unprecedented access to creators James Corden and Ruth Jones as well as the cast and crew as they film the final episodes together as they all say goodbye to this much cherished show.

We’ll also hear from an array of celebrity fans who have their say on the show’s influence on British society and why they believe Gavin & Stacey is the best show on TV.

Gavin & Stacey: A Fond Farewell airs New Year's Day at 7pm on BBC One.
