Dawn and Pete are renewing their vows, so Gavin and Stacey head back to Essex to celebrate. Meanwhile, Gavin becomes uncomfortable with Gwen and Bryn knowing the intimate details of his and Stacey's relationship.

Gavin has a lot on his mind after a heart-to-heart with his father; Dave gets jealous when Nessa and Smithy spend time together.

Dave and Nessa prepare for their wedding. Meanwhile, Stacey breaks some big news to Gavin; and Jason and Bryn finally put their big secret to bed.

It has been ten years since we last went to Billericay to spend Christmas with the Shipmans and the Wests. This year we're off to Wales for the festivities, where Bryn is cooking dinner for over 13 people. Understandably he's tense. Pam would secretly prefer to spend Christmas in Essex, as she finds Gwen's house a bit lacking. But the deal has always been that they alternate every year, and this time it's the turn of the Wests to host Christmas with everyone under one small roof. For Gavin and Stacey, parenthood continues to present them with several challenges, their 'baby' now being ten. Smithy, too, continues to commit to his fatherly role, making the journey to Barry at weekends and every second Wednesday to see 12-year-old Neil the Baby. Nessa, on the other hand, adopts her own brand of Nessa-style mothering, whilst Pam, Mick and Gwen have become the epitome of doting grandparents.
