The Barry folk come to Billericay for the holiday. Gavin surprises his mum and Smithy with news of his promotion in the company's new operation, located in Cardiff.
The wedding day of Nessa and Dave Coaches has dawned, and everyone is looking forward to the big event. Everyone, that is, apart from Smithy, who faces a dilemma.
The wedding day has finally arrived, but whether they will go through with it is another matter; Uncle Bryn may finally admit what happened on the fishing trip; Nessa is conflicted.
Pam and Mick unexpectedly arrive in Barry, and everyone (including Smithy and Doris) decides to spend the sunny day on the beach. But there are two questions on everyone's mind: will Dave be there, and is Gavin really okay?
After his initial angry reaction to Stacey's news, Uncle Bryn agrees to drive everyone to Essex to meet the Shipmans. Pam has laid on a cracking spread and the party goes with a bang, but then Gavin and Stacey make an announcement that throws all the bonhomie out the window..
Pam and Mick are having second thoughts about the conservatory, whilst Bryn is in his element as he awaits the arrival of his houseguests - all the Essex boys down for a big night out in Cardiff.
After being phone buddies for months they finally arrange a rendezvous in Leicester Square, with Stacey's best friend Nessa and Gav's pal Smithy coming along for support
