Fans of Gavin & Stacey were overjoyed earlier this year with the announcement that the much-loved comedy will return for a Christmas special this year.

However, the excitement was tinged with bittersweet news: this episode will also be the last.

James Corden, who co-writes and stars in the show alongside Ruth Jones, shared the news on social media.

It’s been five years since the sitcom last aired, leaving viewers on a cliffhanger when Nessa proposed to Smithy, only for the credits to roll before he could answer.

As we wait until Christmas Day to find out what happens next, a trailer and first plot details have been revealed.

A synopsis shares: “It’s 5 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 5 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.”

The special will see Matthew Horne (Gavin), Joanna Page (Stacey), Ruth Jones (Nessa), James Corden (Smithy), Melanie Walter (Gwen), Larry Lamb (Mick), Alison Steadman (Pam) and Rob Brydon (Bryn) all reprise their roles.

Meanwhile it’s been revealed that Sheridan Smith is set to return for the last episode.

She’ll reprise her role of Ruth ‘Rudi’ Smith, sister of Smithy.

Alongside the final episode, an additional one-off documentary will also air.

We certainly can’t wait to see what unfolds in the final episode!
