The Shipmans drive down to Wales for the wedding fayre. After an eventful trip to church to hear the banns being read, Nessa confides in Stacey her big secret.

The wedding day has finally arrived, but will they go through with it? Will Uncle Bryn finally admit to what happened on the fishing trip and will Nessa do what she knows she must?

Stacey feels dejected because she cannot get a job and Pam tells her she needs to get out more. Smithy needs Gavin's shoulder to cry on because his girlfriend split with him over Nessa's pregnancy and told him she was seeing a younger man anyway. Gavin, Stacey and Smithy head for Barry so that Smithy can go for the scan with Nessa. Smithy lodges with Bryn, who has turned his spare room into a gym and sets about getting Smithy into shape.

Stacey and Gavin are still in conflict over where they should live, with Gavin refusing to even consider the idea of living in Barry. Smithy admits to Gavin that he had another fling with Nessa and realises he's going to have to face her again at the surprise party Bryn is throwing for Gwen. Bryn is panicking because he wants to keep the surprise barn-dance themed party a surprise…but he's also having trouble getting enough people to attend.

Stacey is happy to be living back in Barry as Gavin starts his new job in Cardiff. Smithy tries to adjust life without Gavin back in Essex. Everyone is reunited when the baby is christened.

Those in Essex decide to head for the beach and enjoy their Bank Holiday Monday. Gavin has a heart to heart with his father. Nessa and Smithy are caught by Dave enjoying a good time together.

Nessa and Dave's wedding day approaches. Gavin hears some life changing news from his wife. Bryn and Jason finally deal with their secret. Smithy wishes Nessa all the best as she prepares to get married.
