First image from Gavin & Stacey: The Finale

As BBC reveals the plot summary

Here are the stars of Gavin & Stacey recreating their pose from the original series, 17 years on.

James Corden, Mathew Horne, Joanna Page and Ruth Jones lined up against a wall as they filmed the final every episode, just as they did when the comedy started.

The BBC has released the image as it also published an official description of the 90-minute special – which will air on Christmas Day on BBC One.

The summary reads: ‘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 since then.

‘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 17-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.’
